Hi,

i have have a canon mx870 printer. i have installed it after

http://wiki.ubuntuusers.de/Canon-Drucker

i can only print in 600dpi and in color. i have add in my ppd file:

*OpenUI *CNQuality/Quality: PickOne
*DefaultCNQuality: 3
*CNQuality 1/Super High: "1"
*CNQuality 2/High: "2"
*CNQuality 3/Normal: "3"
*CNQuality 4/Standard: "4"
*CNQuality 5/Economy: "5"
*CloseUI: *CNQuality

but the printer print only standard. if i am choosing economy i doesnt print.

And i have added:

*OpenUI *CNGrayscale/Grayscale: PickOne
*DefaultCNGrayscale: false
*CNGrayscale false/Off: "false"
*CNGrayscale true/On: "true"
*CloseUI: *CNGrayscale

printing in grayscale works. i would like to print in economy also. what can i do?
