Canon 650 not printing duplex

[dth]

When attempting to print duplex the following error is shown: print settings mismatch. Prints one-sided OK. (Prints duplex OK on Windows 11 using Canon Windows driver.)

Help, please.

Hello, automatic duplex printing should work with TurboPrint and the Canon PIXMA G650 printer. A possible explanation is that duplex printing is only supported in combination with "Plain Paper" and standard paper sizes like A4 and Letter.
