I use CUPS (-PDF or -PS) to print graphic documents, drawings,... (especially drawings from QCad which can be printed directly in PS).
I did not find any other else black and white setup than "greyscale". So colours are printed from light (very) grey to black depending on the colour.
I have tried CUPS options like
Code: Select all
# lpoptions -p CUPS-PDF -o saturation=0
# lpoptions -p CUPS-PDF -o blackplot
Some document are so hardly difficult to read.
I had like a setup forcing all in black, and white for the background - i.e. in true balck and white setup instead of a greyscale.
Does anyone already fix this?
Thanks for answering!
Cheers
Charlie
