Too large amounts of data sent when printing images

Adrian, getting 978KB PostScript output out of 400KB PDF input is
normal. PDF is more compact than PostScript. So Ghostscript, Poppler, or
any other filter in the chain behave correctly. So there is no problem
any more on the CUPS/Ghostscript/Poppler/filter side for you any more.
Also the 400kB in
Till, that is exactly what I did. As I said the PS print job size sent
to my PS printer is 978KB. Comment 18 also contains the captured PDF
print job which is 400KB.
If you have any evidence of cairo blowing up images to be 500x the
original image, please file a bug at http://bugs.freedesktop.org/
cosmix, I'm not aware of any printing issues that are caused by cairo.
If you know of any please file a bug at http://bugs.freedesktop.org/ or
subscribe me to the Ubuntu bug.

Adrian, to find out whether the Cairo or Ghostscript is the culprit for
large output files, you need to either print into a PDF file by
selecting the appropriate entry in the printer list in eog's printing
dialog or you should follow the instructions in the section " Capturing
print job data" on h
I tried printing the jpeg file attached with eog and a 978KB PS file is
sent to my printer. So it is more likely that ghostscript is causing the
huge file sizes.
Also, cairo versions >= 1.10 support embedding compressed jpeg images in
the PS/PDF output. But I'm not aware of any applications using
As far as I know improvements on Cairo have been done, but I do not
remember when they were done, whether they were before or after
September 2010. But the improvements in Ghostscript 9.04 should have
made Ghostscript coping much better with bad-quality PDF input than the
Ghostscript of 11.04. So i
Till, following our conversation back in September 2010 (see duplicate
bug, #597338), there are multiple issues with printing on Ubuntu that
persist in 11.04; some may have to do with Ghostscript, but the vast
majority of issues that I have experienced were (and remain) cairo
related, not Ghostscri
Several improvements were done on the Ghostscript as it ships with
Oneiric (version 9.04). Please try an Oneiric live CD (Alpha 3) and
check whether the situation improved. Tell your experience here.
