Bug ID: 464141
Summary: Okular is always printing in grayscale for HP Colorjet
printers
Classification: Applications
Product: okular
Version: 21.12.3
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: printing
Assignee: okular-de...@kde.org
Reporter: dsieb...@mail.uni-paderborn.de
Target Milestone: ---
SUMMARY
***
I can confirm this issue:
https://www.reddit.com/r/kde/comments/x2dhs8/okular_prints_in_black_and_white_unless_i_check/
For me even the workaround with "Force rasterization" is not working. Okular is
forcing the print settings to grayscale even the global setting is set to color
mode. It's a bug between Okular and the HP Postscript driver v3010.107
(built-in driver for Kubuntu 22.04 and latest version in hplip). For the
drivers Foomatic/Postscript and PCL3 the issue disappears, but the drivers are
not offering all possible printer settings. For other programs HP Postscript
driver v3010.107 is working fine.
***
STEPS TO REPRODUCE
1. Use HP Postscript driver like 3010.107 for HP color Laserjet 5550
2. Print a colored page in Okular
OBSERVED RESULT
Printer is printing in grayscale
EXPECTED RESULT
Printer should print in color mode
SOFTWARE/OS VERSIONS: Kubuntu 22.04 LTS
I hope, you can provide us a fix for 21.12.3 since this bug is really annoying
in a productive KDE environment.
