Print on a portable printer

Hi, I need to print (on a portable printer) a payment receipt similar to an app screen.
I have never printed from an app. Can anyone give me some advice on how to do it?

Maybe this tutorial will help you to connect to the printers and print files

Hello Biagio

We haven’t seen any success printing from an App but that’s largely because the App Developer gave up.

We need to know all about your printer, how to connect to it, commands etc.
