Android Question How to print on A4 thermal printer?

[amorosik]

Have any of you already used these printers and can give me some advice?
From an Android app created with B4A, how to send a PDF to the printer?

What price is the paper? It's been about three years since I last bought thermal fax roll (to use in an old analog-ish fax machine for testing non-T38 fax-over-VOIP) and it was not cheap.

On the other hand, inkjet cartridges are not cheap either, so perhaps the all-up cost per printed page is about the same.

I think you need to convert the PDF to image and print with the ESC/POS class

edit: or else you need to request SDK from the manufacturer.

Why not just use the app provided by the manufacturer?

Because we need to send from pc the pdf to phone, that automatically send document to printer
Manufacturer app not expose this function

Price vary in the range 100-200 euro
For paper, 100 sheet around 15 euro (0,15 euro/sheet)
I think that an ink-jet printer, especially a small one, is much more fragile as it has many mechanical components that allow the head to be moved and paper to be loaded
In a thermal printer like those indicated, there is only the roller thar drags the moving paper, everythings is static
