charset thermoprinter "umlaut" like ä, ß, etc

[gurke]

Hi,
I hope this question isn't too stupid, but I have no idea where to find an answer.
I have a thermal printer (https://shop.pimoroni.com/products/mini-thermal-printer) connected to my pi and it's doing fine.
BUT: how do I print german "Umlaute" like ä, ß, etc. ?
Can I just change the utf-coding?

Thanks for your help!

Code: Select all

#!/usr/bin/env python
# coding: utf-8
import printer, textwrap, sys

p=printer.ThermalPrinter(serialport="/dev/ttyAMA0")
unwrapped_text = sys.stdin.read()
wrapped_text = textwrap.fill(unwrapped_text, 32)
p.print_text(wrapped_text)
p.linefeed()
p.linefeed()
p.linefeed()

It looks to have the functionality to change the characterset in the datasheet and the adafruit/Python-Thermal-Printer on github

Hello,
in addition to paddyg's comment, it looks as if this printer supports single byte char sets only. Perhaps better to start with python3 to handle all data in utf and before sending to the device the encoding should be adjusted.
Hope this helps,
