Comment 7 for bug 235399

So, the stars finally aligned, and not only was a cartridge (tri-color, specifically) running low, but I also had the presence of mind to test out the problem. I printed out a black-ink document with KPDF and sure enough, I started getting that purplish pinkish color instead of black by the second page.

Does this mean that this is something like a CUPS issue - or whatever the KDE correlate is?

Is there anything I can provide? Maybe scans of sample printings?
