TTL thermal printer from Python on RPi?

by KJ7RRV on Mon Sep 20, 2021 10:47 am

Hello,

I am working on a project that will basically involve printing a lot of QR codes and some simple graphics using a thermal printer. I'll be using a Raspberry Pi and Python. Will a TTL printer work, or will I need a USB one?

Either will work, but the USB is easier for setup with a Pi especially if you were to use CUPS.

Okay, thanks. I don't plan to use CUPS, and I'm fine with a more difficult setup, so I'll get the TTL model.
