--- Comment #8 from Jan-Marek Glogowski <glogow at fbihome.de> ---
This is a real problem for us. We (City of Munich) generate large mail merge
documents (PDF with 4k - 8k pages, some even 16k), which we want to print from
KDE. Generation using LibreOffice + WollMux takes ~2 hours, but even with the
latest GhostScript 9.15, which is 50% faster then the GhostScript version
shipped in Ubuntu Precise, it takes more then a day for poppler (0.24.x) just
to generate the PostScript to be send to the CUPS server. And additionally we
still have the conversation to PCL for the printer on the CUPS server side. 

Using a printer, which supports direct PDF printing, would get the time down to
just the file transfer time, if Okular would actually send the PDF.

And for some of our test documents the generated PS is much larger (8-10 times,
talking about GB here) then the original PDF, which is written to tmp and
"copied" to /var/spool for local CUPS or send to a central print server.

If you still think this is not a bug, it would be nice to get some code
pointers in current KDE4 okular codebase, so we can probably hire someone to
get this fixed and included Upstream.
