Running Zorin 17 on a Dell Optiplex 7020
Printer is a Canon TS9520
Using both LibreOffice and the default PDF viewer, cannot print duplex.
I have changed the settings in the CUPS GUI, in the Printers settings GUI, and in the page setup in both doc viewer and LibreOffice writer.
The printer will print one side, stop, suck the paper back up and flip it like it is going to print the second side, then spit it out and move on to the next sheet.
No other settings are available, no SUDOs are in any of the websites, nothing I do changes the behavior.
When I tell it to print in reverse order it does (first page on top in the tray) but it will not print duplex.
Canon website is useless.
