Need help in writing a Receipt Printer driver for the Epson POS TM-T88 on iOS devices(iPhone, iPad)?

I write an native application for an iO开发者_如何学CS devices(iPhone and iPad) and want to print to Receipt Printer Epson TM-T88. I can not find any information on how to write a driver for Receipt Printer on iOS devices. Pleas can some one help me out or point out where even to start, thank you all.

Epson provides SDKs for iOS, which should be sufficient in connecting to their printers.

I don't believe the T88 is supported unless you have the Ethernet module to give the printer a TCP/IP connection as I believe that is the only way to print through iOS.

The target printer needs to be "AirPrint" capable. Currently, only a handful of HP printers are capable. I recommend you looking into solutions similar to Printopia.

I need to do this too but this is all I can find on StackOveflow:

Printing to Epson TM-T88V receipt printer from iOS/iPad using CUPS or other framework

Why can I not receive a response from a TCP/IP capable printer?

The 3rd post mentions signing up with Epson Expert to gain access to technical docs etc. The TM-T88 Technical Reference Guide states:

With ESC/POS commands, you can directly control all the TM printer functions, but detailed knowledge of printer specifications or combination of commands is required, compared to using a driver. To use ESC/POS commands, you need to agree to a nondisclosure contract first and obtain the ESC/POS Application Programming Guide. Ask your dealer for details.

It also says this about the TM-T88V Mac Printer Driver:

Mac printer driver allows you to control the TM-T88V using Common UNIX Printing System (CUPS) on Mac OS X.

This MacWorld forum post contains a lot of information about IOS printing via CUPS:
