Xpra trunk does not support landscape printing on OSX

[totaam]

Issue migrated from trac ticket # 995

component: printing | priority: critical | resolution: fixed

2015-10-08 22:42:04: pvenkateswaralu created the issue

With the following versions -
Client --- MacOSX 10.6.8 --- 0.16.0 r10655
Server --- Fedora 21 --- 0.16.0 r10673

I tried to print a gmail attachment in landscape orientation, with size=US Letter. But it still printed the file in portrait, and from almost the middle of the page (the top half portion of the page was left blank). And if the images are big in size (physically), part of it is ripped off/goes out of margins on the right side.

Here's an image of the printed file (.xlsx) captured from my phone.

Here are client/server logs with -d printing

Let me know if any other debugging flags work better for you.

Here's xpra info gathered during the entire session ---> landscape_printing_issue.txt

I tried it with different types of files, and none of them print good with orientation set to landscape.

Files such as .doc, .pdf print properly irrespective of orientation = portrait/landscape, because they are automatically printed as portraits (checked with local fedora machine).

PS: I must mention to you again that printing worked absolutely fine in these versions

Please replace the google drive document with something that is more permanent and versionned, and more simple to read.
You can do tables with WikiFormatting and avoid repeating the same text.
Why is the "Source of Documents" relevant here? Only "Yahoo Email" does something slightly different (print gibberish), which is a different problem altogether. The source of the documents should not be relevant to xpra, only the way we interact with the printing system (browser or plugin or whatever).

What does "Must print in landscape" mean? (that the "portrait" option is not shown maybe?)
Do you get similar behaviour using desktop applications like libreoffice or gedit? Or printing to PDF then printing that from a PDF viewer?

Please include the full server printing log, which will include the setup of the virtual printer using lpadmin.

It looks to me like the PDF step probably uses the correct landscape orientation but that we then lose this information when sending it to the client, then what you get is "landscape printed as portrait".

You can confirm this by running the client with:

XPRA_DELETE_PRINTER_FILE=0 xpra ...

And then attaching the PDF file shown in the logs to this ticket.
ie: from the logs above, this would be:

downloaded 82653 bytes to application/pdf file for printing:
 /Users/maint/Downloads/4ac7540d63071eccf61f8239dced62cfd7c335b6-1.pdf

If it is in landscape mode, then we have to hope that the information is mistakenly dropped somewhere.
Please include the server's cups server log and xpraforwarder log, on Fedora you should be able to grab these with journalctl -f | egrep -i "cups|xpra" whilst you print.

The "Source of Documents" is irrelevant. It was just for our documentation purpose. Thought it would be useful to you in some form. Sorry for the confusion. "Yahoo Email" prints gibberish. But that's how it behaves with any local browser. Its the problem Yahoo itself I suppose.
[[BR]]

What does "Must print in landscape" mean? (that the "portrait" option is not shown maybe?) [[BR]]

-Yes, certain files like .ppt, .xlsx usually print only in landscape. The "portrait" option is shown, but by default, it prints in landscape (tested with local fedora machine).*
[[BR]]

Do you get similar behaviour using desktop applications like libreoffice or gedit? Or printing to PDF then printing that from a PDF viewer?[[BR]]

-I tried it with gedit, and it prints files in "landscape" as expected.*

I have removed the google drive link and added direct links to the documents in the comments above. (see wikiformatting on how to do that, use the preview button to test).

There's still some duplication in that PDF document:

• all tests were done with "US Letter" page size (and I'm not sure that makes any difference anyway),
• portrait printing (the default) always worked,
  So both are redundant for each row and should only be state once somewhere, if at all.

And there seems to be only two types of failures to print in landscape:

• the first two row which state the same thing: Does not support landscape printing. The printed file is left aligned, i.e., it prints the file in landscape, but portion of the fil on the left side is cut off if the files are physically large in size. - do we have a picture of this output? Was the fix on the client or server? (finding a combination that works is good, but you then need to narrow it down further)
• the last three rows which all state the same thing Does not support landscape printing. When tried to print in landscape, the file gets printed from almost the middle of the page, and in portrait. Also, the file does not automatically fit to page, so, sometimes part of the right portion is cut off. Works as expected on local fedora machine. - I assume that this is [/attachment/ticket/995/landscaped_image.png this picture], right? Have you tried older clients with the same server versions? (in particular, a client that is known to print landscape OK from the previous test)

If properly narrowed down, this data could probably fit in a tiny wiki table (assuming a table is even needed), removing the need to download a PDF to understand the point of this ticket.

In comment:3 I see * 'I tried it with gedit, and it prints files in "landscape" as expected.' *, was this through xpra? Which versions?

---

Now, on to the bug proper: the temporary PDF file ([/attachment/ticket/995/4ac7540d63071eccf61f8239dced62cfd7c335b6-1.pdf]) looks fine to me, it is already in landscape mode when it comes out of the print filters which is what we want.
If I send it to my printer from the PDF viewer plugin, it looks OK too. I get the same result if I just print it using lpr.

So for some reason, the client is trying to print it in landscape mode.

Looking at the server log:

parsed printer options: {'sha1': '5134a7a343bfd90046337161a8b031b88706de04', 'printer': '_10_0_11_62', \
    'options': {'time-at-creation': '1444677800', 'PageSize': 'Letter', 'time-at-processing': '1444677800', 'manualfeed': 'off', \
      'edgetoedge': 'yes', 'number-up': '1', 'borderless': 'on', 'manualduplex': 'off', 'ret': 'notset', \
      'job-uuid': 'urn:uuid:6d231c54-f675-3f0c-6ffb-c38e24260624', 'Duplex': 'None', 'lowsupplies': 'continue', \
      'overridea4withletter': 'yes', 'joboffset': 'on', 'Resolution': '300dpi', 'job-originating-host-name': 'localhost'}, \
    'copies': '1', 'title': 'ACFrOgCRGYuEoHSGqFEbkYi7...c2llgppbjb37o2cu7suu57v'}

Which can also be seen later in the client log:

safe print options({'copies': '1', ... }) = {'Resolution': '300dpi', 'PageSize': 'Letter'}

Is your printer configured to print in landscape orientation by default?
Have you tried printing that PDF file directly?
You can also try printing it using the same code xpra uses:

xpra/platform/printing.py PRINTERNAME PATHTOYOURPDFFILE

Where the PRINTERNAME to use can be identified by just running:

xpra/platform/printing.py

(this also works fine for me with the example PDF)
This tool also works on MS Windows where it is just called Print.exe in Xpra's application folder.
On OSX, look for the Xpra.app/Contents/Helpers/Print tool, which should work the same as the Linux one (pycups based).
There is no validation of any kind, if the arguments are not correct then you will just get errors.

As of r10838, you can just use:

xpra/platform/printing.py PATHTOYOURPDFFILE

And it will choose the first printer if there is more than one available.

Note: we may want to include some of the options? things like edgetoedge, borderless can probably be forwarded safely.

Eliminating the need to create a table, I am giving the details the of printed files right here.

I tested the landscape printing on various client/server combinations considering both xpra-trunk and earlier versions (0.15.5, 0.15.6, 0.15.7)

Note: "Portrait" printing works fine in all the cases.

The landscaped prints looked like given below for the versions---

• Xpra-Trunk ---> [/attachment/ticket/995/landscaped_image.png]

• For older versions, i.e., with the below combinations, the landscaped prints looked absolutely fine, except for one file which is a .xlsx file (other .xlsx files printed fine, so I'm not really sure if this is an issue or not). Here's the link to it ---> [/attachment/ticket/995/landscaped_image(.xlsx).png]

  client 0.15.5 10506
  server 0.15.5 r10436, r10445, r10456, r10513

  client 0.15.6 10632
  server 0.15.6 r10656, r10666, r10673

  client 0.15.7 10824
  server 0.15.6 r10656, r10666, r10673

In comment:3 I see * 'I tried it with gedit, and it prints files in "landscape" as expected.' *, was this through xpra? Which versions?
Yes, it was through xpra. I tried it both on xpra-trunk (Client -- MacOSX 10.6.8 -- 0.16.0 r10786
Server -- Fedora 21 -- 0.16.0 r10786) and older versions (Client --- MacOSX 10.6.8 --- 0.15.7 10824 Server -- Fedora 21 -- 0.15.6 r10673). It printed fine in both the cases.

...

Is your printer configured to print in landscape orientation by default?
No, I must specify whether I want to print in landscape/portrait in the settings window. By default, the orientation is set to portrait. File types such as .xlsx, and .ppt are configured to print in landscape by default (the same is the case in local browser as well).

...

I tried printing it using the code xpra/platform/printing.py PATHTOYOURPDFFILE along with Alex, and this is what I got:

Lower priority than the rest of this ticket, but the advice applies to all printing bugs: if there are differences, you need to identify where they come from. Comparing the temporary PDF file is a good start.

Yes, it was through xpra. ... It printed fine in both the cases.

What is the version of OSX, version of cups? etc..
Have you tried newer or older versions of OSX?
Have you tried different printers to see if the problem is limited to this hardware / driver combination?
Have you tried using the Xpra.app/Contents/Helpers/Print tool directly on that system?

Note: as of r10921, we can tweak the default printer options with the client environment variable XPRA_DEFAULT_CUPS_OPTIONS which defaults to orientation-requested=3,fit-to-page=True. Maybe this will help? At least I don't think it does any harm, but since we are now modifying the orientation setting, this will need to be checked with many more cups OS / drivers / printer combinations: checking that this hasn't caused regressions for those that worked previously in particular. (if so, we could consider making the default cups options different for osx - or for whatever printer / cups version is affected)
For example:

XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=6 xpra attach ...

Should print everything upside down. For more details on the cups print options see Command-Line Printing and Options.

In comment:9, your command does not specify the printer you want to use, see comment:7 which explains in detail what to do, both for newer versions of the code (which do not require a printer name) and for older versions of the code (which do require one - and you may want to specify one anyway to make sure it comes out where you expect).

Please learn to use the tracker's comment system, I have had to edit every response you made on this ticket:

• do not reply and quote large amounts of text, we can see it just above - stick to the essential - especially when:
• do not mess up indentation which misplaces quotes and responses, makes it very hard to see who said what when
• if something is not relevant (say XPRA_SIMULATE_PRINT_FAILURE) then don't use it, it just confuses things
• use the preview button and make sure things look ok before posting

When I tried to print that pdf file on the client-side with .. the file got printed in Portrait itself in all the cases.
This statement is a little bit ambiguous: I believe that the PDF used was in landscape orientation already, right? (like this one: [/raw-attachment/ticket/995/4ac7540d63071eccf61f8239dced62cfd7c335b6-1.pdf])
No, the PDF files that are being generated are all in portrait irrespective of what value you specify in XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=x.
[[BR]]
Let's clarify a few things:

• when we want to print in landscape orientation, we make the PDF rotated 90 degrees so that when we print it in portrait orientation on the client (we always print in portrait orientation client side) it will come out in "landscape" orientation - a PDF viewer should show it in portrait orientation but with the contents rotated 90 degrees. (see your first example PDF attached to this ticket)
• the XPRA_DEFAULT_CUPS_OPTIONS is a client switch (see comment:12) which is applied when submitting jobs to the local printing system - yet you seem to be expecting it to have an effect on the PDF conversion filters, which run on the server side (also, you're not including the full command lines, so it's impossible to even try to reproduce what you did) - it was added to try to force the printing in portrait mode (and to be able to test different settings)

Why have you switched from printing the calendar to printing a picture? Does it make any difference? (it confuses me for sure)
As I said above, the calendar is in "landscape" orientation already (or "rotated 90 degrees"), the [/attachment/ticket/995/995_fileThatGotGenerated.pdf picture] is not. (note: this filename is nor particularly helpful to identify what we are meant to be looking at). Why is that? What changed and when?

---

I downgraded the server version to r10972 and with this, I was able to change orientations, page size, etc in the printer-selector-settings-window.
But with server revision r11058, the behavior is still the same. I can't change orientations, page size, etc. I haven't tested with server revisions between 10972-11058 though. Please let me know if I have to narrow it down further to find out in which revision this problem started.
[[BR]]
Sounds like this should not be too hard to bisect then.

Note: from the screenshot attached, it looks to me like the printer dialog should allow you to select orientation: the popup window is shown with the 4 options.
If you are saying that it is impossible to select those options using the mouse using an OSX client, then this has absolutely nothing to do with printing, this would be a window focus bug, reproducible with many other dialogs - which may well have have been reported before.
You should be able to confirm that by using the keyboard to activate those options.

You should also be able to connect two clients at the same time with sharing enabled, then you could use a Windows or Linux client to access the orientation dialog (that's assuming that the bug is OSX specific), confirm that landscape printing works on OSX then open a new bug about the popup menu not working (or re-open/add to an existing ticket, if appropriate).
If you are still having problems with landscape printing on OSX, try the printing tool on the client, feeding it the PDF as generated. (the one that should be rotated 90 degrees) Then if that still doesn't work, try to use the XPRA_DEFAULT_CUPS_OPTIONS to see if you can force any orientation at all (or even other options).

I'm sorry for the mess. I will try to explain the issue as best as I can and keep it as short as possible.[[BR]]

As of Client-16.0-r11176-OSX10.6.8 and Server-16.0-r11160-Fedora21
[[BR]]

• It is true that the OSX client did not allow me to select orientation in the printer dialog (and I will either open a new ticket or add to an existing ticket about the popup menu not working).

• So I tried to connect two clients at the same time with sharing enabled (Fedora 21 and OSX) : Fedora21 to access the orientation dialog and OSX to perform the print. By doing this, the PDF generated looked like [/attachment/ticket/995/4ac7540d63071eccf61f8239dced62cfd7c335b6-1.pdf this] which is rotated 90 degrees. But the actual print looked like this

• Feeding the PDF as generated (the one that is rotated 90 degrees) to the printing tool on the client using ./Desktop/xpra-trunk/16.0-[r11176](../commit/0b6dd77c94baf53f258d985597427c9d4a8c4a28).app/Contents/Helpers/Print _10_0_11_62 /Users/maint/Downloads/4ac7540d63071eccf61f8239dced62cfd7c335b6.pdf prints similar to this picture

• Trying to force the orientation using XPRA_DEFAULT_CUPS_OPTIONS also results in the same. PDF generated is rotated 90 degrees, and the actual print is from the middle of the page -> like this

[[BR]]
Just to be clear: XPRA_DEFAULT_CUPS_OPTIONS has no effect whatsoever on the PDF generated, this is a client print job control option. See the last two line from comment:19, which uses bold font for highlighting this.

OSX uses the same printing system as Fedora (cups).
Using the print tool directly, please try different OSX machines and different versions of OSX to see if they are all affected or just some.

Note: for following the debugging instructions below, you may also need to remove the postscript-printer and/or pdf-printer which may have been added to /etc/xpra/xpra.conf during installation. (but not on OSX, where there is no such file).

It may also be worth testing the server with:

XPRA_PRINTERS_GENERIC=0 xpra start ..

Which may generate a PDF that looks the same, but is slightly different (maybe the metadata carries the orientation?) as it should end up using the "old" cups-pdf method. (can be confirmed by looking at the printing debug log, when the printer is added and configured).

r11196 also makes it possible to specify which mimetypes will be handled by the print filters, maybe restricting to postscript rather than PDF can workaround this issue? (in which case we could quite easily make this per-platform) Hopefully without too much quality degradation or regressions.
ie:

XPRA_PRINTING_MIMETYPES=application/postscript xpra start ...

So... made the mistake of getting ambitious and trying to test with newly set up fedora 23 server. Fumbled with this and that, but was never able to get printing to work (for now I'm assuming that I'm just missing a new fedora 23 detail).

Timeliness failure disclosure out of the way — I'm afraid the "landscape printed as portrait" theory you mentioned above does still seem to be happening. (Not sure if it ever got truly confirmed, maybe I should have tried my hand with this ticket earlier.)

Going back to my old ways... tested with 0.16.0 r11304 osx client against 0.16.0 r11366 fedora 21 server.

Printing the arbitrarily chosen lawn gnome at http://www.privacysurgeon.org/blog/wp-content/uploads/2013/04/Garden-gnomes-e1365011986402.jpg in landscape mode... using firefox, I essentially get the landscape image printed horizontally across the middle of a page formatted in a portrait format ("landscape printed as portrait", I presume).

Meanwhile, with XPRA_DELETE_PRINTER_FILE=0, I get a significantly more "landscape-y" pdf file not being deleted from the client (attached).

..set up fedora 23 server. Fumbled with this and that, but was never able to get printing to work..
[[BR]]
It would be good to know what the problem is with Fedora 23 before the 0.16 release. Anything in the system log? Any errors in the xpra server's -d printing log?
Maybe a package dependency is missing? cups filters? selinux was disabled?

---

Since there is no mention of it, I assume that the printer dialog does let you select the orientation and that the problems related to this were just a different issue (see comment:22).

---

The attached gnome PDF looks like what you expected the printer to output on paper I presume?
So the server side is just fine, the problem only occurs when the OSX clients submit this PDF for printing, as it seems to get rotated again when it should not be.

As per comment:21, things left to try:

• using a different PDF rendering setup via XPRA_PRINTERS_GENERIC (and verify it does get used)
• using postscript
• tweaking the locally submitted print job via XPRA_DEFAULT_CUPS_OPTIONS

Please also verify that other tools (PDF viewers? a local browser?) can print this file as-is. (my local Fedora desktop can, it looks fine)
Just to make it 100% clear: the PDF is rendered with the correct horizontal orientation already, simply printing this document in "regular" vertical orientation should give the expected output on paper. Why OSX insists on rotating it once more without us asking is what we're trying to figure out.

Ok... testing some more with osx 0.16.0 11503 client against 0.16.0 r11366 fedora 21 server (I'll do more testing to see if it's just that I've missed something with the fedora 23 server or if there is maybe an issue once I get a chance... I suspect I just missed something).

• I tried with the XPRA_DEFAULT_CUPS_OPTIONS tweaks, but it kept coming out landscape as portrait.

• I tried to print locally ($ XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=4 ./Print _10_0_11_62 /Users/Schadenfreude/Downloads/0d6e0381698caeab50a41782fd9926b89542c346-3.pdf, as well as without the default options, or with the default options=5) ... to no effect, still printed landscape as portrait.

• I tried with XPRA_PRINTERS_GENERIC=0 xpra start ... - again, landscape as portrait.

• I tried with XPRA_PRINTING_MIMETYPES=application/postscript xpra start ...... and it worked as expected/hoped?!?!

I'm not sure if you need logs, but I'll slap down some from the working option, just in case.

The comment above was still missing the test of printing locally, so I dusted up the ol' mac mini and hooked up the printing and found that:

• chrome browser prints fine
• safari opens in it "Preview" which also prints fine (as can be seen in the preview page)
• our "Print" pycups wrapper has the problem
• so does the default system "lpr" utility

So I guess what we could also use a more (or is it less?) "clever" print queue helper. So I went looking for one and stumbled upon this: Mac OS: print PDF in landscape orientation from command line - which talks about an ominous but I have to switch off "rotate automatically".
I tried various options:

• lp -o landscape -o fit-to-page -o media=A4 Downloads/test.pdf - OK!
• lp -o landscape -o fit-to-page Downloads/test.pdf - OK!
• lp -o landscape Downloads/test.pdf - OK!

So then I tried with our "Print" wrapper tool and found that despite what the documentation says, we should not be using the numeric values for orientation, so this works (and r11516 removes the invalid default option from the code):

XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=landscape /Volumes/Xpra/Xpra.app/Contents/Helpers/Print ./Downloads/test.pdf

Which sounds great.. except we have no way of knowing when to activate this workaround: all the server knows about this print job is this:

xpraforwarder[6880]: running: ['xpra', 'print', 'socket:/home/tlaloc/.xpra/jimador.spikes.eng-13', \
   '-', 'application/pdf', '0d6e0381698caeab50a41782fd9926b89542c346', \
   'Garden-gnomes-e1365011986402.jpg (JPEG Image, 598\xc2\xa0\xc3\x97\xc2\xa0300 pixels)', '_10_0_11_62', '1', \
      'edgetoedge=yes manualduplex=off overridea4withletter=yes manualfeed=off number-up=1 \
       joboffset=on Duplex=None Resolution=300dpi PageSize=Letter lowsupplies=continue borderless=on ret=notset \
       job-uuid=urn:uuid:fc94d726-18b1-3e1e-42e1-5f9abcf17394 job-originating-host-name=localhost \
       time-at-creation=1450748346 time-at-processing=1450748346']

That's because the PDF is already in the correct orientation by the time it lands in the print queue, and it should be printed as-is.

I am reluctant to change to postscript at this point... especially after the 0.16 release.
And the change in r11517 is a little bit big too, because it's done cleanly using the per-platform files, I guess something more hackish could be merged in 0.16.
Some other minor improvements in r11518 and r11519 will give us a lot more printing debug information via the print tool and via xpra info. (trunk only)

@afarr: please confirm that trunk prints in lanscape mode correctly for you. (works for me, I have many many gnomes printer all around the house)
And that this does not cause regressions in other areas (quality, or whatever) as the rendering pipeline is a bit different for postscript..

Trunk is printing as hoped/expected with 0.17.0 r11535 osx client and 0.17.0 r11580 fedora 23 server (yes, looks like I'd missed some fedora 23 set up details, all good now), whether I use the local variable or not to set the default value. (I think I need a lawn for all these lawn gnomes...)

Note, when I use the above listed local printing option (i.e. XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=landscape Xpra.app/Helpers/Print PRINTER_NAME ~/Downloads/test-garden-gnome.pdf) to try to landscape print a pdf (rather than a .ps) the 0.17.0, then it still prints "portrait as landscape".

While running in general to see if there might be any other impact, I haven't been seeing anything in a (relatively brief) stint of testing, but I did see a server-side traceback that may be related (not sure what triggered it, since I wasn't seeing anything particularly dramatic while "side-testing" video and browsing rendering).

I will backport the switch from pdf to postscript for osx (which is what "fixes" landscape printing).

Noted the lack of effect from the XPRA_DEFAULT_CUPS_OPTIONS=orientation-requested=landscape, I will try to find the time to play with this again, but not going to worry too much about it since we have a working fix.

For the "failed to freeze" error, see #835#comment:26.

Backport to v0.16.x in 11593.
Also pushed a beta osx build with this change, can you please check that this doesn't break anything before I post the next 0.16.x stable update.

Looks like there're some sound bugs in the 0.16.1 builds.. and a vestigial "frozen" variable bit (maybe from fix moved to 835).

Put details into #1076.

The "frozen" bit should be fixed, in any case it should not interfere with printing.. except that the log will fill up very quickly and make it hard to work with.

Ok, tested with lots of those "run all night" and all the other functionality that I could think of... looks good and stable for 0.16.1 release (testing with 0.16.1 11604 osx client against 0.16.1 r11617 fedora 23 server). Also tested printing with 0.16.1 11604 windows client, seems to work as expected.

I think it is good enough to close this ticket.
