Other projects • Re: Thermal Printer Firmware with RPI 3a+ Troubleshoot

Glad you got this, ame. This looks like a bog-standard 701 thermal printer. They all talk the same commands

For simple, ASCII-ish text only it's faster to use these without CUPS. They only have a 8600 baud interface, and sending bitmaps over that is slow.
Thanks. No worries. We have established the correct port, correct wiring (I think) and correct baud rate. Next is selecting the language and character set. If it works with hard-coded ESC-POS commands it will work with something more complicated if necessary. Unfortunately, providing assistance via a forum is a slow process, like playing "Twenty Questions" by pigeon post, but we'll get there.
