I seem to recall that, when printing to my colour inkjet, I would have the option to change things like resolution, paper type, etc., on a job-by-job basis, from the print dialogue. So, if I changed from glossy photo paper to plain paper, I could set this from the KDE print dialogue that would come up when I clicked "print" in my application.
I noticed recently that, instead of getting the numerous paper options I used to be able to choose from a long list of paper types ("Plain Paper", "Photo Quality Inject Paper", "Ilford Heavy Paper" and about a dozen others) the paper type in the settings dialogue only has two options; "Plain Paper" and "Transparency". There is also no option at all to change the resolution (i.e., from the default 360x260 to 1440x720 or something else more suitable for photo printing). These options are available when setting up the printer driver intially, but I assume I shouldn't need to reinstall the driver every time I need to change from matte to glossy paper in the printer. I uninstalled and reinstalled the printer, thinking this might help. One think I have noticed in the initial setup is that there is an additional option I don't recall seeing before, "Controlled by Printout Mode". Not sure what that means. I had a look in the kdeprint manual, but couldn't find anything on point. I can't pin down exactly when I lost this option, as I don't use this printer very often and do periodic updates to the box. I am running current unstable w. KDE 3.1.2, using CUPS. The printer is an Epson C40UX inkjet, and I am using the Foomatic + gimp-print-ijs driver. Bruce
