PIXMA G6020. Yesterday, 4/21, printing with no problems. Today, 4/22, cannot print from the cassette. I have ensured all settings are correct, etc. etc. How ridiculous. I'm trying to work from home and this is creating serious problems for me.
Found my solution here. Printing from Adobe was fine, my problem started with Word. See:https://support.usa.canon.com/kb/index?page=content&id=ART174811&cat=MEGATANK_INKJET_PRINTERS&actp=LIST&showDraft=false
