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https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=94 In addition, of that, the command itself is obsolete.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) opw-3351084,3341907 X-original-commit: f30085b

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:
Most of the code is inspired from
python-escpos. Using the library to print the receipt have the same drawback: https://github.com/python-escpos/python-escpos/blob/master/src/escpos/escpos.pyDue 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).
The options are:
IMC= Image Mode ColumnLDV= Low Density VerticalLDH= Low Density HorizontalSCALE<XX>= Image Scale in percentage (for instanceSCALE50is half the size of the receipt printer)In the case of the TM-U220 on which the fix was tested the name could be set as
TM-U220_IMC_LDV_LDHwhich would give:(the picture goes off of the receipt horizontally)
or
TM-U220_IMC_LDHwhich would give:( fully fit on the receipt but text is hard to read)
