Printing bugs is correctly a bit annoying thing to work with, also
because it might be a bug in all over the stack and it is at least not
something I'm likely going to prioritize that high on my own

in okular, it starts from generator_pdf

Okular::Document::PrintError PDFGenerator::print(QPrinter &printer)

and then it on unix likely ends up in 
fileprinter.cpp in FilePrinter::doPrintFiles

where it actually tries to execute lpr in many cases if you aren't forcing 
rasterize. 


/Sune
 - also sune@d.o and sune@k.o and others, currently hacking on Poppler
   and Okular quite a bit
