> Bug description:
>  Printing takes too long, or occasionally fails. During the print job,
>  process gs takes 100% cpu and printer pauses for a long time. This
>  happens on Ubuntu 10.04 32bit on a 500Mhz Pentium 3 with 312MB of ram,
>  on Ubuntu 10.10 64bit on a 2.4Ghz Q6600 quad core with 4GB of ram, and
>  on Ubuntu 10.10 32bit in a virtual machine with 1024MB of ram. Both
>  printers I have are affected. Officejet Pro 8000, Canon iP4500.
>  Printing is faster in 8.04 LTS.
>
>  The attached PDF seams to cause particular problems and takes about 10
>  minutes to print. The gs process is using 100% cpu all this time.  I'v
>  noticed that the drop shadows in the attached document aren't always
>  printed. But this document isn't the only one affected. Photos and web
>  pages also pause during printing in draft and photo print modes.
>
>  I read the instructions here
>  https://wiki.ubuntu.com/DebuggingPrintingProblems to disable apparmor
>  using 'sudo aa-complain cupsd' but this made no difference.
>
>  I've just tested an old Apple 8500 which is a postscript printer.
>  Printing takes a very long time to start, and process pdftops uses
>  100% cpu during all this time if this is of any relevence.
>
>  Printer test page works fine.
>
>  I've noticed this mainly affects documents with objects that are
>  blurred and transparent. Eg. create an object in inkscape and set
>  opacity to 80 and blur to 40; and the printer becomes lethargic. A
>  shape with opacity set to 100 and blur set to 0 prints in the blink of
>  an eye.
