Even when I pick Greyscale in the Printout Mode under Resolution it still says something like: 300 dpi, greyscale, Black and Color Cart. This leads me to believe that the color catridge is used for greyscale printing or it is just a ripoff by HP to get us to by more ink.This seems to be true for many HP printers, but not the Deskjet 710C (see http://its.truman.edu/news/newsletters/HP_Deskjet_grayscale.stm ). When I select grayscale from the kdeprint dialog, shouldn't send a black & white image to the printer anyways? Or does it still send thecolour image but (supposedly) flag a grayscale option in the driver? It doesn't appear to do either, in my case.
I have a DeskJet 712C which I think is the same basic thing. Bear in mind that it isn't a real printer that takes postscript, instead it uses a special program to produce the printer commands and ignores feedback from the printer[calling it a 'driver' is /very/ generous]. Personally, I have 4 'printers' set up[w/ lprng]: bw, bweco, color, coloreco,[and ascii]. The printers use different filters which have different options to pnm2ppa to do the right thing. If I want a black and white print out, I tell the program to print [color] to the bw printer. If KDE tries to 'flag a grayscale option in the driver' on its own it will probably fail.
Then again, my printer filters are all in /usr/local/bin/ so it is probably a 'nonstandard' setup.
