As mentioned in comment #11 there's also the pdfprintpdf branch if someone
wants to give it a look.

Two other approaches to reducing the use of ghostscript are

Yes, printing with 'rasterization' does not require ghostscript.

Could somebody clarify if the recently merged "raster" printing patches would
avoid using ghostscript? Distributions are discussing to phase out ghostscript
because of security issues, see e.g.

I just did a quick test and generally it works and sends the PDF to CUPS. So
thanks again for this quick patch.
I currently don't have time to turn this patch into a really useable version
and I don't know if anybody will add enought priority to it and work on it (I'm
leaving for a holiday at least until July).

The initial patch would be great. We'll get this tested before production
anyway and I can report back or probably even send patches, which fix stuff.

It's not that we're not coding stuff ourself, but I thought it would be more
work to get this coded, and we already buy Linux support, which patches
upstream code, if we don't code the stuff ourself.

Additionally I would add some option to okular to select the default printing
format (PDF or PS - like LibreOffice) to really get this feature included
upstream (defaulting to PS). We normally require upstream / master fixes before
including a backport in our release, so we don't have to re-patch everything
within our next major release cycle.

Changing the pdf printer to just pipe the pdf file is quite trivial, you should
not really need to hire anyone for it since it's a 5 minutes patch in
PDFGenerator::print

The problem is testing that everything still works, since sure, you're use case
may get better, but there's lost of other people printing out there and it may
break for them.

I can give you the five lines patch and then you donate to
http://kde.org/donate instead of hiring someone to code it, but i do not think
i have enough stamina to test all the printing test cases, is that something
you could help with? (i.e. printing smal documents, different page sizes into
different page sizes, etc)

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.
