--- Comment #13 from Wolfgang Bauer
Followup to comment#9: I created a new printer in CUPS now on my system (Leap 15.1 with the latest Qt 5.13.1) using the hp-color_laserjet_pro_m252-ps.ppd file.
When I opened the print dialog in Okular, the Duplex option was available.
But then I changed the default paper size to "Custom" (0 x 0) in the CUPS settings (http://localhost:631), and the Duplex option was disabled in Qt's print dialog.
So I'd recommend to check and play with the default printer settings.
Oops, the wrong printer must have been selected when I tried the second time... I actually cannot reproduce the problem. If I change the paper size, the Duplex option is still available, it just shows a warning icon if I select one of the two duplex settings. -- You are receiving this mail because: You are on the CC list for the bug.
