I understand that the reason for different drivers for different printers is because different printers have different resolutions and different command sets. The command sets could be harmonized just as all modems worth considering use the Hayes standard command set. Resolutions could be harmonized because it's already been done for screens of differing resolutions. So why not have a single printer command set and a driver that can easily handle different resolutions? If 2 (or preferably more) major printer manufacturers got together and designed such a system, others would have to follow to be competitive, so come on Canon, Epson, HP, Brother, Kyocera, etc., who's going to make the first move?
