Hi

I'm trying to print a PDF in duplex to a remote network printer.
However, the duplex options (long side and short side) are greyed out.

Evince and Libreoffice do allow selecting duplex, and indeed print duplex.

It seems an issue with some printers only. (Maybe it tries to query the printer, but can't?)

lpoptions correctly reports that it should do duplex by default.

I'm now pretty sure that this is a QT issue.
I build the notepad QT5 example, and it had the same issue.

How to proceed?
