[poppler] Printing of certain PDF files does not work with "fit-to-page" because of wrong BoundingBox values in the PostScript

You mean "for your printing needs", some other people would argue that most 
users want the thing they print to fit in the paper they're using, and to be 
honest "fit to paper" is evinces default print mode too.

Anyhow any talk about okular is off topic here, if you want to help with the 
development join okular-devel 
  https://mail.kde.org/mailman/listinfo/okular-devel

If you want to file a bug, that's also welcome but less likely to yield 
results.

Cheers,
