ESC/POS printer with flutter desktop application?

Question

Folks we are developing Flutter windows desktop application it is the Point of sale application in this main feature is printing we can find lots of resources on ESC/pos topic in the android flutter application or even through method channel we can access the printer but in windows its quite challenging where and how to start so far we have used https://pub.dev/packages/printing this library which prints but the length of the print is limited to the size of the A4, so even I have tried to run ESC/pos command through cmd using dart but no luck can anyone help me out where to start ????

Thanks in advance !!

That's probably because the printer is set up as a Windows Desktop page printer. Try setting the printer to serial port connection mode and installing the serial port driver instead of the Windows printer driver. And if you modify flutter's escpos printer library to handle printing from the serial port of your local PC, you'll be able to print. — kunif

The serial port is USB vendor class mode. You should be able to install and use the serial port device driver using that mode. Alternatively, if you are connected via Bluetooth or LAN, you may be able to use flutter's escpos printer library without modification. — kunif

The printing plugin has support for 80mm and 57mm prints. The most common width size used for thermal paper receipts is 80mm. You can then set the page using PdfPageFormat

Page(
  pageFormat: PdfPageFormat.roll80,
  build: (Context context) => SizedBox(
    child: // Receipt contents
  ),
),
