I had a really good canon pixma printer a while back. I was sharing a computer with my husband who likes to play video games on it. I went 2 weeks without printing something, and he happened to install a game on it. I went to print something, then it started doing that but not just no black, TOTALLY distorting all colors all together. I thought it was the printer that went, so I got a brand new HP printer. Same exact thing, so I reinstalled Photoshop, same issue. Now I'm on a different laptop and it just started doing it again. I've spent HOUUURSSSS upon HOUUURSSSS printing on different settings, paper, everything.

I've cleaned everything, ran every test, IDK if I'm just not on the right Photoshop settings when I print or what, but it's driving me crazy that I can't figure it out AT ALL.
