Another big, "Thank You", to redogg! Just received the Canon Selphy CP900, today, and was up and running in short time. It took a bit to understand Canon's jargon like, "access point", when all I really wanted it to read was, "your wifi network".
Successfully printed wirelessly from iPhone5 and Nexus4 (after downloading the Canon Selphy apps), and wirelessly from my MBP. Also printed from SDHC card inserted into the printer, but haven't gotten around to connecting the MBP, via USB cable, to the printer. I have not installed the software that came with the printer, since I don't really need it, or its abilities....maybe someday.
Thanks again, redogg!
