I can't print to my HP DeskJet 2720 printer. I keep getting a "paper mismatch" error. But the printer has A4 paper loaded, and the documents I'm trying to print are A4 size. I've tried several applications, including Work, Adobe (PDF), and the HP Smart App. I'm printing from a Windows 10 laptop, and the printer defaults are all set to A4 paper size in the main tray. I have tried deleting and re-adding the printer, but that doesn't work.
