- Edited
I just tried Long edge and Short Edge flip on my TS5350a and it doesn't seem to make any difference it is upside down with either option.
Edit: Just printed a PDF 2 pages from the Canon App on my Android phone and the long edge 2 sided printing works correctly the print is correct way up.
Edit 2: Just tried Win 11 over wifi and it wouldn't print a test page so downloaded the latest driver from Canon and now it prints properly with a PDF double sided and correct way up. This is why I hate Windows.
