Since one year, I am being using a Canon MPS460 all-in-one printer, connected to a PowerPC G4, Mac OS X 10.4.11. Last month I run out of colour cartridge and set the G4 to print all black and white. Since then, I have replaced the colour cartridge but I am non longer able to print in colour. Note that the Print Preview of the file to be printed appears in colour; and the nozzle test of the printer is correct. I have tried all I could think of, including the reinstallation of the printer: no success.
I suspect that there is a missing command or preset in the Mac, however, I cannot find it out. Any clue?
