/*
 * Windows:
 * COM1
 *
 *  For linux devices it is best to do: dmesg | grep tty (This will show you your available serial devices)
 * LINUX:
 * /dev/ttyS1
 *
 * RASPBERRY PI with PISERIAL
 * /dev/ttyAMA0
 *
 *
 * If you have issues with the font be garbage on the page then you will need to change Port Speed
 * // Windows
 * Open Start -> Computer -> Right Click -> Manage Computer -> Devices -> Ports -> Find your port and click Properties -> Click Configure -> Edit the Settings
 * OR
 * Open CMD -> Windows Key and R -> CMD -> Enter -> MODE [SERIALPORT]:[PORT SPEED],N,8,1,P
 * For reference: http://www.computerhope.com/issues/ch000245.htm
 *
 *
 * //LINUX
 * You might want to try: stty -F /dev/tty[PORT] [SPEED]  however linux is usually out the box and it works.
 *
 * PLEASE NOTE: On Linux you may need to do: chmod a+x /dev/tty[DEVICE] as by default you only have Read Access to the Coms port

//For this example I am using my Raspberry PI
$printer = new phpprint("/dev/ttyAMA0");
//We put a space between the top of the page and the content
$printer->newline();
// We set the font to something that I would define as slightly more sexier
$printer->set_font(phpprint::FONT_B);
// We then set the justification to CENTER - This will print everything center aligned
$printer->set_justification(phpprint::JUSTIFY_CENTER);
// We now set the font larger for our Text Logo
$printer->enlargePrint(true);
// We simply add our text for the logo (Note: The \n will ensure the next piece of content will go to a new line
$printer->text("FuelledUK EPOS\n");
// We are changing the font to show you the difference
$printer->set_font(phpprint::FONT_A);
// We print some more text to fill the page
$printer->text("www.fuelled.co\n");
// Lets add some space before we start placing with Colours
$printer->newline();
// We are now telling the printer we want everything to be printed in opposite. So black background and white text
$printer->reverse_mode(1);
// Generate Random ID (Test only)
$rand = rand(200000,999999);
// As you will see there is slightly bigger space between the text so that it looks good on the print out
$printer->text("   CUSTOMER ID: ".$rand."    \n");
// We now reset the printer back to normal printing mode
$printer->reverse_mode(0);
$printer->enlargePrint();
// We then apply 2 lines of space. Feed is best for when you want bigger gaps
$printer->feed(2);
// This function will generate you a barcode - Simply specify the content, barcode type and height
$printer->generateBarcode($rand, phpprint::BARCODE_CODE39, 80);
// More spacing
$printer->feed(2);
// Add some normal text to the page with different font
$printer->set_font(phpprint::FONT_C);
$printer->text("NEW CUSTOMER: WARREN DOYLE\n");
// Always ensure you add space at the end of the print so you can easily collect it from the printer
$printer->newline();
// Finally cut the page
$printer->cut();
// If you are creating multiple pages, I would ensure you put
// sleep(1); so that the print doesn't get congested and stop working

echo "Print succesful";
