For a embedded linux project i wrote a printer driver for a custom thermal printer. Everything worked fine. I have a device /dev/thprint now and i can just write pixel into this device and its actually printing this pixels (just a bit array with a fixed with of 384 pixels). The next step is now to make a cups raster driver, so i can use it as "real" printer. I looked up many examples but i just don't understand where to specify which device to use. Does anybody have an example how to do this ?
