I have Android app, which is working very well with English printing from the thermal printer. The code is perfect. But the problem is when I pass Arabic characters or any other Unicode it does not print properly.

The problem is with a code page. I tried different codepage which supports Arabic as well as Unicode while converting strings to byte. It shows the proper string in the log also of Arabic, but when It prints it does not work.

Note: My printer supports Arabic and codepage is 32. I need a universal printer solution. I am not using Epson SDK. I am using ESC/POS commands.

Answer 1

most easy would be to use the Epson SDK; because it does not care if it's an Epson printer - only the vendor ID in the device-filter for USB devices differs in between the vendors; but Star Micronics and other 100% compatibles work just fine. if you want to write your own driver, which literally means re-inventing the wheel; have a look at ESC/POS appendix C, page 73:

for Arabic you'd need to select character table 13 with the ESC t command, which is IBM code-page CP864. the sequence would be: \x1B \x74 \xD. the output also would have to be encoded as CP864, converted from UTF-16, so that it matches the code-page, which the printer then expects.
