I’ve got an HP Photosmart C4780 printer that used to work fantastically…but now everything it prints, it turns GREEN.
This is not good. I can’t print out green lineart/illustrations to color!
I have absolutely no idea what to do. It doesn’t print anything for the ‘clean printheads’ or ‘test page’ options when I select them, and this hasn’t ever happened before. I even manually cleaned the ink cartridges, but no deal.
Any smart people out there have an idea?
