I also tried to run the Python script as root and although it does not ask me for my password, it still doesn't keep my changes. If I knew the file to which it is trying to save, I could try to edit that file instead. The list of valid values for that field are defined here: I found this file: /etc/cups/ppd/hp_color_LaserJet_2550.ppdīut changing the DefaultColorSpace to Gray in that file has no effect. In case of Apply you immediately see the problem, it does NOT save the change (it reverts right back to Color.) If you hit Save and come back, same thing, it's still on Color and not monochrome as just saved. In there, I can click on Job Options and on that screen I see defaults, including the print-color-mode which is set to Color.Ĭlicking on the dropdown, I can select monochrome and then click either Apply or Save. So I looked around and found that I had to go to preferences, printers, right click on my LaserJet 2550L and select Properties. Downgrading is always a very annoying feature update! However, no such option appears in the newer version. Although I had to remember and change the setup each time I would print, since I rarely print color documents, it wasn't that bad. Since I upgraded to 13.10, I cannot print in black and white anymore.īefore, the driver would give me an option in the Print dialog. I have had an HP LaserJet 2550L for a long time now.
