Re: [Printing-architecture] The Common Printing Dialog and PDF as standard print job format for Qt/KDE applications

Hi,
sorry for delay, but our next product is upcoming, and sometimes time
is getting short at the moment at my side. :-)

I noticed that you couldn't fully dispel all my arguments, and
therefore I think you caugth the issues.

Still I've some comments to your last e-mail...

But the PDF-1.7 reference from Adobe is written so:
http://www.adobe.com/devnet/acrobat/pdfs/pdf_reference.pdf

It could be viewed only (and only with acroread) after the file was
completely downloaded.

Sorry, but how is the printout on non-brandnew or non-PDF-able printers
done?
Isn't there a conversion to older PDF versions or to a printer
specific rasterization necessary?
Which tool do you think is used for doing so, if not xpdf?

What about the JPEG2000 support (PDF-1.5)? I doubt that it is
multi-media related, and having doubts regarding "non relevant
feature" classification either.

What about the layering? I got bugzilla entries where the layering in
some newer PDF versions produced wrong printouts (different then in
viewer). I.e. https://bugzilla.novell.com/show_bug.cgi?id=377878

A technique, which was introduced with PDF-1.6, I think.

I agree. But I heard about this rumor quiet some time now, and got
doubts that it will ever be done.
