Before this commit:
When printing a receipt with an epson printers models TM-U2X0 (like
TM-U220), random characters will be printed instead of the receipt.
This happened as a picture of the receipt is sent to the IoT box, but
the TM-U2X0 models does not support all "Bit Image commands". We
currently use the GS v 0 one which is not supported by this printer
models. See:
https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=94
In addition, of that, the command itself is obsolete.
After this commit:
The support for another command "ESC *" is added which is not obsolete
and supported by TM-U2X0 models.
Notes:
- Compared to "GS v 0", the receipt printed with "ESC *" is worst:
- It take longer to print (5 seconds vs 1 second)
- There is consistently some thin "empty white lines"
- Most of the code is inspired from `python-escpos`:
https://github.com/python-escpos/python-escpos/blob/master/src/escpos/escpos.py
Due to the drawbacks, making it the default way to print would be a bad
idea. As such, we can configure the mode (with other parameters) using
particular name for the printer (which can be done by adding it manually
with cups)
