#!/bin/hi *

I have an HP Color LaserJet MFP m278 which does duplex printing. In the System Settings, I can specify duplex printing and the printing dialogue like in Okular when printing a PDF. However, in the System Settings, I can choose a type of duplex printing, whereas in the printing dialogue of okular I can not: long or short edge binding options are greyed out.

Yet, opening the document on the same machine using the same CUPS settings in Document Viewer of Gnome GTK prints duplex flawlessly.

I think this is a problem in okular, not printer setup.  Please check with the latest versions in Plasma6.
