We need to be able to create PosCodeTable. It seems to me that not all printers have the same code tables. I need to use greek on epson printer. Check here for epson code pages. https://reference.epson-biz.com/modules/ref_charcode_en/index.php?content_id=1

I would like to be able to do something like PosCodeTable(15).

it seems to me that even if i alter your code to pass 15 for greek it is still not printing for invalid character

Hi,

Have you tried to encode your text before sending it to the printer using charset_converter package? Here are some examples: https://github.com/andrey-ushakov/esc_pos_printer#using-code-tables

You are right, different printers may support different code tables and/or have different codes for them. It's better to check your printer's specifications (usually you can print a ticket listing all the supporter code tables).
