make unsupported printers work with xp drivers and ddiwrapper

Some (most?) printer manufacturers still don't make printer drivers for Linux, or just for a few models or low quality drivers. This make people running into trouble when migrating to Linux. There is a program called ddiwrapper (developed bij SUSE) that can use the XP drivers in Linux to make printing to unsupported printers possible (at the moment only Canon drivers seem to work). Add ddiwrapper to Ubuntu and change it in such a way that extracting/installing of the xp drivers is easy, because it is seem to be quite hard to get it up and running, but if installed properly it seems to be working quite well.
