Provide some context as well (Android version, kernel, etc.).

First the obvious: are Chrome versions on both your phone and PC up to date? You probably don't need Chrome on the phone but it's worth a shot anyway.

Delete Cloud Print's data or reinstall it to eliminate any issues there, you may need to downgrade via apkmirror. The problem may very well be on the PC side as well. Try Googling the exact error or wait until someone with more experience on the matter can give some insights. I can't test right now as I'm on the Oreo train.
