@Rabeeh96
I had worked around creating a widget with my specific design requirements and take a screenshot of this widget and then send it to the printer to print it as an image.

@MustafaGamalAbbas after capture big size of bytes image does your printer stuck ?

MustafaGamalAbbas commented 3 years ago

@ul-rotha it depends on the quality of the printer and the status of the internet, but for me, I had tried to print an invoice 1m long, and it works well.
