Hi
I posted this yesterday on the KDE mailing list, but received no opinions. So I'll try to repost here:
I have a weird problem in KDE's printing dialog:
My printer is shared via a printserver on a OpenSUSE running as NAS/server/host whatever, using CUPS and Avahi. After configuring cups and avahi on the client machine it picks up any printer announcement and makes the printer available locally.
I have verified that Avahi announces the printer capabilities as Duplex True.
klaus@msien:~> avahi-browse -c _ipp._tcp --resolve | grep -i duplex txt = ["printer-type=0x901E" "Duplex=T" "Color=T" ...
Firefox and LibreOffice picks up this, and I can select Duplex Long or Short edge as expected. But trying to print from Konqueror or Okular any duplex option is grayed out and selection is stuck on Off.
However: If I open the Firefox printing dialog, select Long edge and press Cancel, then immediately enter the print dialog in Okular (or Konqueror), I can now select Long or Short edge print (and it the printer does duplex as requested)
I am runnning KDE Frameworks Version 5.105.0, Qt Version 5.15.9 (built against 5.15.9), cups-2.4.2 on OpenSUSE Tumbleweed.
Any opinion if this bug is in OpenSUSE, KDE, or maybee CUPS?
I'm guessing that you are using the automatic configuration feature available with modern printers. You might try instead the traditional, static, configuration. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
