KM C3350i and duplex print from linux cups

[i-have-fax-problems]

I've installed the ppd for C3350i on a linux system.
I simply can't find where to active the duplex unit.
The 1-sided 2 sided button in my app (libre office) remains grey.
I cant select 1 or 2 sided. I've searched through cups. I can't find something
like Duplex Unit installed or uninstalled.

What I do wrong?

Set Mac Print Driver to Default to 1 Sided on Bizhub MFP - YouTube

does your cups look similar?

Thank you.
There is the button "Print Type" under "admin" then "finishing" too where I can switch from 1-sided two 2 sided,
but in the application (Libre office in this case but with other apps there is the problem too) the 1-sided 2 sided button
remains grey. You can't switch it.

Thank you,

KM Support gave us another ppd, which solved the problem.
Seems the ppd you can download from km website has this bug.

Any chance you can share these files ? We have the same problem, CUPS just plain refuses to change printer to 2-sided mode

While it may be best to get an "approved" ppd from KM, you can always try OpenPrinting - OpenPrinting , as they have quite a few ppds available.

I have used them quite a few times for ppds that I've used in Mac, Linux, UNIX, and even Windows.
