Android Question Print label Xpriner XP-420B

[Lakhtin_V]

I am trying to create an Android application in which I need to print thermal labels on a printer Xprinter XP-420B. I want to use Bluetooth as an interface. I have already tested the printer in operation on smartphone, through a special application, printing labels via Bluetooth is performed. But how can I now achieve printing of the GR code and text on the label, through my application. Are there suitable examples?

What printing method or instruction can help me. Actually I want to print a picture(QR) and text fields next to it. I thought up a plan to create a label layout in Activity. Then save the rectangle from Activity as a picture. Then I will send this picture to thermal printing, first I will stretch it to the entire size of the label. What will be easier to do - a copy of Activity as a picture or a copy of Activity as a PDF file for subsequent printing?
