Well, color printing being three times as slow as black would make sense, actually. Example: say you have a PgS page that is supposed to be all black text. If you use the black ink cartridge and driver, it only requires one pass of the printhead for each line. If you use the color cartridge/driver, it requires -3- passes of the printhead to print the 'black'. At least three times as slow, probably more. The way the color cartridge makes 'black' is to overprint all three colors. This results in a dark dark green, rather than BLACK too. I suppose it depends on what type of color you are using? If you are just using spot color (either color hilighting on borders, adding a color bitmap, a color headline, etc) and the rest is black, then I'd suggest doing the multi-pass. Create two pages; one with all the pure black stuff, and print that. Then the color stuff, and overprint. So long as the registration can be a few dots off (that's REAL small) I've found that to work like a champ. Worth a shot anyway. –jp–seattle–
