Reliance on electron-printer/node-printer

[mattkrins]

This library works brilliantly for printing to networked printers, however I would like to print to a local printer too, but due to the reliance on electron-printer/node-printer this is not possible as these libraries are dead/broken and pull requests are ignored.
Is it possible to print locally without electron-printer/node-printer?

let printer = new ThermalPrinter({
  type: PrinterTypes.EPSON,
  interface: 'printer:myprinter',
  characterSet: 'ISO8859_2_LATIN2',
  removeSpecialCharacters: false,
  lineCharacter: "=",
  options: {
    timeout: 5000
  },
  driver: require(electron ? '@thiagoelg/node-printer' : 'printer')
});

I'm using it this way, I just had to do a few extra steps because when I installed the node-printer library I couldn't find it in the node modules folder.

I used it with that "node-printer" because if I used another one, the driver couldn't find two methods that I don't remember exactly which ones, I think they were getPrinter() and directPrint(), don't believe me but it was something like that, so I used "@thiagoelg /node-printer" because it did work, but when executing the Electron project it gave me an error, so I had to install "Desktop development with C++".

i fixed it with this

I don't know or believe that what I did is the best practices but it solved the problem for me.

After installing the VS I did this

npm install --save-dev electron-rebuild
npm i @thiagoelg/node-printer
electron-rebuild

I tried until "electron-rebuild" passed the "node-printer" correctly in the end I got some errors but I didn't pay much attention to them and when I ran the electron project "node-printer" I no longer got the "self error" and I was able to use the "node-thermal"

Thanks for the advice @Wolyo , I tried a similar method but got errors when trying to package the project which i couldn't resolve, but the dev env worked fine.

I found another workaround today which is going to suit me better:
On the host running node-thermal-printer share the local printer like you would to the network, but only set permissions for the local user, then for the ThermalPrinter interface just use '//localhost/LocalPrinterName'. No extra library required this way, but it would still be nice to not need workarounds.

Maybe we could build a new C++ Node.JS library for local printers across the 3 platforms. Printer are ancient at this point and finding reference code wouldn't be too hard. I am looking to do things over the network primarily but testing has been a pain since I use a wired one. thiagoelg/node-printer seems to be fine, but a more maintained one would be nice.

@mattkrins An awesome workaround! Thank you!! It works!
