Hello there, I recently purchased a CanonPixma MX340 and it claims to be capable of printing at 4800x1200 dpi which I'm sure it can do. I'm not sure however, of how to set it up to do that. On my old printer, I could manually set it to print at whatever dpi it was capable of. On this one, my only options are fast, standard, and high and high seems to be nowhere near the level claimed. Any help on this issue?
