Hi all, this is my first post on here but hopefully it'll solve a few problems.
I've had the same issues with the Canon IP5200 and have tried using the Gutenprint drivers but have found that the wireless functionality was poor (when connected to an Airport Express). Also, when connected via USB, the printer will not produce as good photo prints compared to when using Lion OS.
After much searching, swearing and threatening to chuck the thing through the window I've found the official Canon driver for the IP5200 on the Canon USA website: http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_ip_s eries/pixma_ip5200#DriversAndSoftware
After installing, removing all previous incarnations of the printer in my printer list, I reinstalled the driver downloaded from Canon - works a charm! Both wirelessly and vis USB. All the original functions are back including ink levels, advanced options etc.
Hope this works for anyone stuck in the same rut.
Cheers
Kris
