Has anyone an idea, how to force users to print b/w on a color printer. We are in the process to deploy color printers to some of our offices where they use centos 5.5 as their OS. They need the printers to print some advertisement material. But for everything else, they don't need it. And because of the costs of the color printing we would like to force them to use B/W where not explicitly necessary. Is there a way to force a printer driver to be just B/W even if it is a color printer. So i could install a second color printer which would only be available to a special print user.
I assume that this is printer dependent. So I'd look at man lpoptions and try listing the various options available lpoption -p <printer> -l and look at storing the needed options in ~/.cups/lpoptions or /etc/cups/lpoptions
For example, on my HP L7590 (color all-in-one):
$ lpoptions -p home-printer -l PrintoutMode/Printout Mode: Draft Draft.Gray *Normal Normal.Gray High High.Gray PhotoBest PhotoHigh PhotoNormal InputSlot/Media Source: *Default PhotoTray Upper Lower CDDVDTray Envelope LargeCapacity Manual MPTray PageSize/Page Size: Custom.WIDTHxHEIGHT *Letter A4 Photo Photo5x7 PhotoTearOff 3x5 5x8 A5 A6 A6TearOff B5JIS CDDVD80 CDDVD120 Env10 EnvC5 EnvC6 EnvDL EnvISOB5 EnvMonarch Executive FLSA Hagaki Legal Oufuku w558h774 w612h935 Duplex/Double-Sided Printing: DuplexNoTumble DuplexTumble *None Quality/Resolution, Quality, Ink Type, Media Type: *FromPrintoutMode 300ColorCMYK 300DraftColorCMYK 300DraftGrayscaleCMYK 300FastDraftColorCMYK 300FastDraftGrayscaleCMYK 300GrayscaleCMYK 600ColorCMYK 600GrayscaleCMYK 600PhotoCMYK 600PhotoNormalCMYK 1200PhotoCMYK
So I assume that setting option Normal.Gray instead of Normal (the defaullt) would give me gray-scale printing.
YMMV, of course.
