I have an EPSON TM-T70E (Ethernet) pos printer. I'm using the ios SDK and I can print everything ok. But I want to be able to print Greek Characters. So I must change the character set the printer is using. In the iOS SDK I can't find any way to change the character set. So I was thinking about sending direct ESC/POS command to make the change. The problem is that documentation is very poor and I can't find a way to send direct ESC/POS commands to the ethernet version of the printer. Can someone please provide some directions?

  • If you open a socket to the ip address, port 9100 (typical default), you can send direct esc/pos. is this what you are asking for? – rlb Jun 11 '13 at 10:21
  • I guess so. The command I want to send is: ESC T 17 ( I think this is the character set for greek ). Can you please help on how to do this? – Panos Jun 11 '13 at 10:35

  • I can send the esc command as string? Do I put spaces or not? – Panos Jun 11 '13 at 11:32
