--- Comment #9 from [email protected] --- I have conducted some tests and analyses. I saved a very simple file containing a yellow rectangle from LibreOffice as a PDF. I printed the file using both Okular and Firefox. The following files were created in /var/spool/cups: cxxxxx print control file dxxxxx print file Okular prepares a PostScript file for printing, while Firefox creates a PDF file. The latter file is much smaller than the original file. Both files ultimately display the same, correct content. The color is correct. Therefore, the color change must occur during the printing process in CUPS. The print control files could be the culprit. Unfortunately, they are binary encoded and I don't have a decoder. It's noticeable that the file generated by Okular is much larger. Looking at the files as hex dumps, it's clear that Okular has the setting "print-color-mode: colorD" configured. No other settings related to "color" are present. "colord" was not originally installed on my computer. The /var/log/cups/error.log file also contained messages like: "CreateDevice failed: org.freedesktop.DBus.Error.ServiceUnknown:The name org.freedesktop.ColorManager was not provided by any .service files." However, installing colord did not resolve the issue of incorrect colors. -- You are receiving this mail because: You are watching all bug changes.
