Not sure why you call it UK 'Rip OFF'lousy service.
If Canon choose not to offer a plug-in for another companies software there's no way you can call it a UK Rip Off. If you really want a plug-in for Photoshop Then Canon in Oz will supply it as a download. Plug-in for Photoshop
Personally I think that Photoshop provides equally as good printing as Canon, so why bother with a plug-in?
