When printing from PS CS5, I no longer see the choices for Canon papers in the print dialog on my Mac Pro. I recently upgraded my computers to Mountain Lion. My laptop still shows the Canon mp620 profiles so I can print from there. If I knew where to find these profiles I could reinstall them on the MP. Thanks.
Printer profiles have to be specific to the combination of printer/ink/paper you are using. You need to look to the manufacturer of your printer paper for the profiles you need for your specific printer model.
Turns out that after moving my computer and printer to a new house, then connecting the printer wirelessly, the computer was pointing to an out of date driver. Deleting the printer and reinstalling the newest driver fixed the problem. This was discovered with the help of a Canon phone rep.Thanks.
