Mac os 10.15.5 new Pixma G7020 wired LAN, communicating fine per IJ Network device setup utility, was able to print earlier today
now when I try to print - test page at end of setup, word document, Adobe Reader doc, Outlook doc - The document connects, but does not print because "The printer is in use"
I have tried resetting the printer
readding the printer
resetting the printer and repeating the entired setup https://ij.start. canon
turned the printer off
restarted the iMac multiple times
I called Canon support
verified that there was no job being printed despite error message
verified that printer was connected via wired LAN - communicating normally, unplugged USB (Catalina sometimes does not recognize printer when USB connected )
in printed set-up went to wired LAN: manual set-up and disabled IPv6
printed from Word document - worked
The excellent Canon tech representative said that sometimes on home networks the printer gets confused when IPv4 and IPv6 addresses are available. disabling the IPv6 should not be a problem and will prevent miscommunication in future.
The printer has worked fine since.
