Maximum PC: Canon decided to update its PIXMA printer line with just four weeks to go before 2012 moves into the rear-view mirror. There are three new printers in all, including two wireless all-in-one models -- PIXMA MG6320 and MG5420 -- and a wireless photo printer -- iP7220 -- along with a new CanoScan 900F Mark II Photo Scanner that's capable of scanning up to 9600x9600 dots per inch (DPI) for film and up to 4800x4800 dpi for all other media.
