[cups] Printing 2 copies on a double sided printer

[Axel Braun]

Hi,

I have a PDF with a single page. I want to print 2 copies.
The printer prints by default double sided (long edge binding).

Result: 2 copies are printed on one paper (front & backside)
Expected result: 2 copies are printed on 2 separate papers

Printer is a Brother MFC 9340 CDW, 'Force Rasterisation' on the Okular/KDE
print menu creates indeed 2 copies!

I had addressed this in https://bugs.kde.org/show_bug.cgi?id=425289 , KDE team
says it is an upstream issue.

CUPS version is 2.3b6 - any idea what I could do?

Thanks
Axel
