Printing black-and-white

How can I do black-and-white-only printing for even color sources?

Most pdf filre are colored, but acroread doesn't has the option to let me choose to print black-and-white-only.

I tried the following in acroread printer command configuration, but still, acroread prints color outputs.

/usr/bin/lpr -P my_printer -o saturation=0

Please help.

Can I give my printer an alias for black-and-white-only printing, and use that whenever I want to print black-and-white?

thanks

You should have a file /etc/cups/ppd/xxxx.ppd, where xxxx is the name you have configured your printer with. Please post (an URL to) this PPD.

Printing black-and-white

Well, the PPD offers to select one of two color models: CMYK color and Grayscale:

*OpenUI *ColorModel/Output Mode: PickOne
*OrderDependency: 10 AnySetup *ColorModel
*DefaultColorModel: CMYK
*ColorModel CMYK/Color: "<</cupsColorOrder 1/cupsColorSpace 8/cupsCompression 1>>setpagedevice"
*ColorModel Gray/Grayscale: "<</cupsColorOrder 0/cupsColorSpace 3/cupsCompression 1>>setpagedevice"
*CloseUI: *ColorModel

Thus, if your printer is configured properly, you simply could (either by using the lpadmin command or the "configure printer" from the web admin) set the default color model to Grayscale. You could even edit your printer's PPD "by hand" by replacing

*DefaultColorModel: CMYK

*DefaultColorModel: Gray

And you may easily set up two print queues - one configured for color printing and the other for b/w printing as indicated above - pointing to the same physical printer.

Please RTFM. The saturation (and hue) options only affect image printing (not PostScript).

The brightness option *should* work, but with the sample drivers the effect might not be all that noticeable…
