So my printer that has been fine for years suddenly printed black instead of blue today. The ink was low so I thought it was that and put in a brand new ink but it is still printing black. The only thing I'd done different was to open a pdf that I'd created in Coreldraw and pull that into my Photoshop file and that's the item that shows as blue on the screen but prints as black. I created a new file and drew a blue square but that printed black too. Any ideas how to fix it?
