Title:
Colour casting on black text using the default renderer pdftops
(workaround: use gs)
Status in poppler package in Ubuntu:
Incomplete
Bug description:
For some time now (I think the bug is not specific to Ubuntu 12.10 but
also present in 12.04), I am having trouble when printing black text
with an HP Color LaserJet CP1515n, that worked fine on previous Ubuntu
releases and from other Operating Systems. The output is kind of ok,
but black text does has a slight red cast, making it look fuzzy. The
problem exists when printing from LibreOffice, Firefox and Evince.
Trying different settings and drivers to debug the problem, I came to
the conclusion that the problem is on the pdftops default renderer. On
LibreOffice, I went to File - Printer Settings - Properties - Device -
Printer Language Type and chose Postscript (Level from driver). For
Firefox and Evince I just used this command from the command line:
$ lpadmin -p "HP-Color-LaserJet-cp1515n" -o pdftops-renderer-
default=gs
(use "pdftops-renderer-default=pdftops" to restore the default)
Using this settings (gs), the printing results are fine.
