Just a heads up. (I am unsure if this deserves a separate new bug report). Last night I updated from Ubuntu 11.10 to 12.04 LTS. I have the same issue as the original poster. Just to reiterate:
1. This printer (The HP Laserjet 3600n) was working normally in Ubuntu 11.10, although I don't remember which driver it had chosen. 2. Upon update to 12.04, all print jobs would print 2 pages. The first was empty, the second contained this error in the upper left: PCL XL error Subsystem: KERNEL Error: IllegalTag Operator: 0x45 Position: 7 3. Upon checking the driver (Right-click the printer, select properties, click Make and Model), it recommended to use the "pxljr" variety under HP Laserjet 3600. 4. Upon selecting one of the other options (either "hplip" or "hpcups") under either the "3600" or "3600n" variety, the colour is always incorrect, including the test page. Specifically: The "C" is printed in pink; the "M" is printed in brown; the "R" is printed in green; the 4th color circle (bottom right) is a pale blue outline of a circle with no contents; the "K" is black; the "B" is a different black with a bluish tint; and the final test mark is a series of 4 10% pie-pieces ranging from dark gray to medium-light gray. Printing an image that displays in medium blues on my screen comes out red/pink/purple/white. Please advise as to whether I should report a new bug. I am not well- versed in bug reporting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/977457 Title: hplip in Ubuntu 12.04 beta 2, HP color laserjet 3600 prints wrong colors To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/977457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
