Description Thomas Witt 2012-10-17 09:19:13 UTC 
When I print the attached pdf (or any other one using the nexus font) the characters of each entire line get placed on top of each other. This is even visible in the print preview.

Printing the same pdf from the hplip Device Manager directly it works as expected. 

Reproducible: Always

Steps to Reproduce:
1. open attached test.pdf in evince
2. press print, print preview

Confirmed both with evince-3.4.0 and 3.6.1, and reported upstream at https://bugzilla.gnome.org/show_bug.cgi?id=686324

new example

I installed cairo-9999 and that made it much better, the character spacing works now, but I'm still getting the little box instead of the page number and the equation-counter.

@cairo maintainers, please add the following two patches from upstream git:

http://cgit.freedesktop.org/cairo/commit/?id=cffbdf50ce0117d62d6e157369c60e4a8572fd21
http://cgit.freedesktop.org/cairo/commit/?id=599e78ea2ee146c74fc7ffcee32a055dabbefdda

Applying these two patches to cairo-1.12.2-r4 fixes the issue with incorrect character placement in pdf printing from evince.

1.12.6 is now in CVS.
