Thanks for the link Kai-Uwe, although I'm not sure what suggests it is a vendor driver issue from there (but I'm far from an expert). That link does confirm the colour issues in this bug on the affected OS.
Comment #10 here shows the testing by Gyuris that with the same official driver the printer works perfectly with Cups under 10.04 - 11.10, versions 1.4.3 - 1.5.0, but following a change in 12.04 / Cups 1.5.3 it prints very strange colours. FWIW I'm running on i386 - officially supported OS by Xerox. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/984424 Title: Xerox WorkCentre 6015 wrong colors cups 1.5.2 Status in “cups” package in Ubuntu: Confirmed Bug description: Xerox WorkCentre 6015 Ubuntu 12.04 cups 1.5.2 sends the wrong colors to printer.
