As of the release of Final Ubuntu Dapper this printer has FULL compatibility, even the direct printing to CD/DVD works. Not only does it have full compatibility, but the end results from all my print's have been (much) better than their Windows counter parts.
You shouldn't need any help to get the normal everyday printing working as it's now plug & play, but here's a quick howto that I wrote for getting the direct printing to CD/DVD working.
I luv this printer 😀
***EDIT*** – Added the howto to the main page, just to save anyone the trouble of going off site.
