I tried to print a big .djvu document, first I have printed only odd pages from 1 to 399 and everything was fine, but then I tried to print even pages on the back side. During my first attempt okular inserted a few blank pages and all next pages numeration was broken. I reprinted broken pages and tried again but again similar result (please see attachments. Reproducible: Sometimes Steps to Reproduce: Try to print some document on the two paper sides as described above. Expected Results: Okular should print as expected and should not spoil the papers and ink. Should be much more reliable in this case.

Turns out it was not us being unreliable
