This works successfully [OpenPrinting/MacOSX/hpijs] BUT when I originally installed it, it would only print in colour [i.e. it only used the colour cartridge to print, even to print black/white or greyscale]. I solved the problem - I thought - using the advice from
http://tech.ifelix.net/1300.html even if my printer was on the "compatibility list".
However, I recently installed the latest version of the OpenPrinting software [http://www.linuxfoundation.org/en/OpenPrinting/MacOSX/hpijs#Printers] to find that I have reverted to the colour cartridge only use! I don't seem to be able to resolve the problem this time around. Can anyone help?
