It's been a while since I've programmed such a printer and unfortunately can't supply any of the code. But normally Epson thermal printers are sent a monochrome image as the source for the print.

There's a lot of work from PoS hardware providers to standardise the use of peripherals. One such attempt is OPoS.

Try searching for OPoS printer drivers and APIs.

Often because of the requirement to work with proprietary technology such as embedding point of sale systems, thermal printer APIs are documented at quite a low level and work with bit/byte messaging instead of traditional methods such as page printing with GDI+.

The supplier should be able to refer you to the documentation for the printer which outlines the messages which are supported by the printer.

Printers normally run on parallel, serial or USB connections. You'll most likely need to open a socket via the relevant port type and then implement the messaging as described in the printer documentation.
