Many people own color printers today; they are so cheap, there is little point to buy a B&W model.
But I don’t want to print with color by accident. If you’re using Linux with CUPS, here is a solution: lpoptions
“lpoptions -l | grep -i color” will tell you what the color options and possible value are. My output looks like this:
ColorModel/Farbmodus: *CMYK Gray Colorreprod/Farbwiedergabe: *Printersettings Textgraph Textphoto Vivid Publications Lineart MediaType/Media Type: *PrnDef Auto Plain Transparency Labels Letterhead Bond Color Preprinted Prepunched Recycled Cardstock Vellum Envelope Rough Thick CoatedPaper Highqlty User1 User2 User3 User4 User5 User6 User7 User8
To change the default, use “lpoptions -o”:
lpoptions -o ColorModel=Gray
The first command tells you the new default:
ColorModel/Farbmodus: CMYK *Gray
CUPS saves these settings in the file ~/.cups/lpoptions.
