Comment 2 for bug 496080

You might try to adapt the .ppd file like I did for my c5380. My patch for the hpcups .ppd for the Photosmart C5380 can be found attached to the bug report:
https://bugs.launchpad.net/hplip/+bug/785199

In particular, I think that the \cupsReal0 and \cupsReal1 (which define the overspray setting for borderless printing) settings are important to get rid of the clipping.

With those changes applied, printing to DVD works fine, except when you select the DVD tray as the default tray (the filter will then ignore that tray default and NOT use the DVD tray). That's an unrelated bug, though.

Cheers,
