Epson LQ-500 360 180 ribbon cartridge ($5) http://support.epson.com/hardware/printer/dotmatrix/lq500_/index.html us-ascii A epson I configured it using the RedHat "printtool" program. I selected "Epson Dot Matrix, 24 pin" and the 180x180 resolution output. 360x180 also works, but it's slower and doesn't look much better.
