I can confirm a very similar problem however this was in Edgy and the printer being used was a HP Deskjet 940C.
The problem was that by using: System -> Administration -> Printing menu to go in and change the printer properties, in this case default print type from normal to normal grayscale would have no effect in the printer's ppd file or anywhere else for that matter... resulting in the printer always printing in color. By manually changing the "*DefaultPrintoutMode" from "Normal" to "Normal.Gray" we were able to create a workaround. -- changing settings (like paper size) have no effect in CUPS https://launchpad.net/bugs/52017 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
