Trintech make credit-card terminals which run on embedded Linux. Although it is relatively easy to set up the hardware to run on Linux (many manufacturers make drivers for Linux) i.e. the touch screen panel, it CAN be less straight forward for the scanner. Most EPOS (Linux) uses the standard EPSON codes for printer (ESC codes= Epson Standard Codes) but there can be difficulties with getting the fonts correct- sometimes graphics can display incorrectly. We hope to be able to supply a touch screen EPOS LINUX based system in late 2005- early 2006. Hope you find this blog of interest….
