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. -- Dale Dellutri -------------- next part -------------- An HTML attachment was scrubbed...
