A simple CUPS driver for the Epson TM-T20 POS printer. Epson provides a driver for this printer, but they only provide x86 and x64 linux binary builds instead of source. As a result, the driver can't be used on ARM systems, such as the Raspberry PI.
This is a very simple driver that provides buffered raster printing and paper cutting at end of page or end of job.
To compile this on a raspberry pi, you will first need to install two cups dev packages: sudo apt-get install libcups2-dev sudo apt-get install libcupsimage2-dev
