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:
