Description Unknown 2014-06-26 22:19:00 UTC

Hello,
this is my first bug-report, so please give me some clues, if i am doing something wrong in this bug-report.

OS: openSUSE 13.1, 64-bit, KDE 4.11.5, Linux-Kernel 3.11.10-17-desktop
Software: Okular 0.17.5
Hardware (printer): Canon i-SENSYS MF4340d with UFRII/UFRII LT driver for Linux Version 2.80

Problem:
Sometimes i get some PDFs with QR-codes in it (e.g. train- or airplane-tickets, university-certificates, etc.). Using Okular i can open and view these PDFs properly, but i have trouble to print them nicely. Everything is printed well, except of the implemented QR-code - the QR-code is just a black box with odd stripes in it.

Reproducible: Always

Steps to Reproduce:
1. Open a PDF (with QR-codes in it) with Okular
2. Try to print this PDF using a Canon-printer
3. Watch the printed result
Actual Results:  
The printed QR-codes are just black boxes with some stripes in it.

Expected Results:  
The printed QR-codes should look like QR-codes :-)

Maybe there could be a problem with the Canon-printing-driver in combination with Okulars PDF-backend, because i never had this printing-bug with my old HP-printer.

Workaround: I don't have this problem, when i am using Firefox or GIMP to view and print these PDFs.

Since i found out, that i get the same problems, when i print self-generated QR-codes out of LibreOffice, i guess it's just a printer-driver-bug.

So, i think, it's not a KDE or Okular error.
