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.
