This requires knowledge of the printer’s control codes. Some printers  
are  
controllable solely by way of their data stream, some are not. If you  
knew  
the specifics of the printer, and you knew it could be controlled  
entirely  
through its data stream, then a pure Ruby program could be written to  
control it.

It looks like you can download a user manual for it from

[Epson® Official Support](http://www.epson.com/cgi-bin/Store/support/supDetail.jsp)?  
BV\_UseBVCookie=yes&oid=14245&infoType=Doc

The user manual link is above this description:

This document contains an overview of the product, basic and in-depth  
usage instructions, information on using options, specifications, and  
control code information.

With that information it should be possible to get something going.
