The option of Photo Paper Plus Double-side (PP-101D) will not be available to Mac users of iP1500 and iP2000 due to a Mac OS limitation which dis-allows a manual duplex prompt message for users to turn over the paper physically.
Notice for Mac users of all Canon printers
The option of Photo stickers (PS-101) will not be available to Mac users due to the unavailability of the software requirement for Mac OS.
