  HP (Hewlett-Packard) (Printer)
  Mint (older version)
  Works perfectly
What doesn't work:

solved: printing in colour mode results in blurry black printing, greyscale works.

What was done to make it work:

bug reported on launchpad (https://bugs.launchpad.net/hplip/+bug/889306), workaround available, bug fixed within next regular release of Ubuntu (12.10) and following derivates.

Additional notes:

needs Plug-in to be downloaded, sometimes site was not accessible
