Pi Zero seems overkill to me for a printer.


It costs $20 and comes with wifi and bluetooth. Seems like a valid choice to me.


An ESP32 is way cheaper and has Wifi and BLe as well. I updated a label printer with an ESP32-S3 to add wifi[1] and it has plenty performance. It is even available with dual-band wifi 6[2]. Most processing is done outside the printer on the sending party anyway.

They are largely sold out, especially at quantity. Not something I would currently be looking to base a product on.
