Minor CUPS tidbit - black and colour output

I was reconfiguring my HP PSC 1315 printer on my laptop today (as I had reinstalled Debian) and I accidentally stumbled on a minor issue I had been encountering all these days namely why I had been getting the colour cartridge to produce black text. This had been making printing slower and reducing the quality of the black output. I had simply left the Resolution, Quality, Ink Type, Media Type setting in Set Printer Options (in the CUPS interface) to "Controlled by Printout Mode." So it was either using the colour cartridge or the black cartridge exclusively to produce the output regardless of whether the page contained black or not.

Just changing this simple setting to another option (like "300 dpi, Color, Black+Color cartridge") fixed the issue. I thought it was a hpijs driver limitation, but it turned to be a configuration mistake on my part all these days.

Now I can print a mixture of pure black and colour on a single page and don't have to keep changing the printer options every time I want pure black printouts - something that had been bugging me for a long time now.

Just thought I'd make a note of this here, since I'm likely to forget this over time. This should also help others who've been having the same problem and wondering why they don't get pure black printouts by default just like in Windows.
