Howdy. Brand new here. I'm trying to print from my new MacBook Pro to my office's networked Canon ImageRunner 2800 printer. I've downloaded the driver, PPD_v2.55.hqx, from Canon, but when I try to open it with StuffIt, I'm told it can't expand the files because of an archive problem. StuffIt does produce a us_eng.sit file but that is just full of gobbledygook text. When I try to add a printer, I select 'more printers' which makes my Mac scan for installed printer drivers. It then lists Canon IJ Network as an option but allows me no choices to do anything with it except cancel (the Add button is grayed out). At wits end. THanks for any help.
