I have a feeling this has nothing to do with opensuse, but HP has been no help and I hope someone here has experience with this.
It appears that my yellow cartridge is not working on printing. I get no red or yellow at all and everything has blue-green tint. I have run the cleaning program many times but the problem persists. The test page prints black cleanly but where there should be red, it is gray. There is a brown block which I’m guessing should be yellow. My printer is an HP Officejet 6700 Premium all-in-one. So, I put a photograph on the scanner glass and, using the printer’s keypad, made a copy of the photo. While the colors were not great, both red and yellow printed in the copy. I have the latest hplip installed.
I have loved this printer and can’t afford to replace it right now, at least not with one that has similar features.
