Well I bought one of these last week with some Ilford Gallerie Prestige smooth pearl paper. The paper is a semi-gloss and I've been very impressed with the output so far although I've only printed two shots.
I've installed the Ilford ICC profile for the paper and printer combo, but I couldn't figure out how to use the profile with the Canon printing app. I might have more success with Photoshop.

Take a look at the Printers and Printing Forum at www.dpreview.com as there has been a lot of posts regarding this printer, new firmware issues and colour casting to B&W prints
