Forgive me if this has been answered already. Please point me to the relevant post.
I am trying to use lpoptions to set the default print mode to B/W. Works fine when I use the web interface but lpoptions doesn't seem to have any effect.
My printer is a networked HP LaserJet (and is the system default) and when I do (as root)
I get a list that includes
PrintoutMode/Printout Mode: Draft Draft.Gray *Normal Normal.Gray High High.Gray Quality/Resolution, Quality, Ink Type, Media Type: *FromPrintoutMode 150BestColorCMYK 150ColorCMYK 150DraftColorCMYK 150DraftGrayscaleK 150GrayscaleK 300BestColorCMYK 300ColorCMYK 300GrayscaleK 600BestColorCMYK 600GrayscaleK
So I expect that when I do
lpoptions -o PrintoutMode=Draft.Gray
the default colour mode should be "Draft Gray". (Yes, I have restarted the CUPS service too, in case that mattered.) Yet, when I open an application and do File->Print and check the options it still says "Color".
When I make the same change through the web interface I see the change immediately. What am I missing? Please.
