10.6: Restore features on older multifunction printers
Authored by: jjardoino on Nov 27, '09 11:25:34AM

I found another way to restore printer functions in 10.6. I found it after installing the true Canon driver for my S800 (because the Gutenprint driver supplied by Apple is very bad and prints dark pages). I could print with the Canon driver, but not access to the printer's options. But the printed result was much better than with the Gutenprint driver.

Then I discovered that, when printing with an app which was runned in 32 bits mode, I had access to all the printer's options (quality, choice of paper...). The Canon driver for S800 is not given to be compatible with 10.6, but it works with 10.6. It's not 64 bits.

When opening the print window in an app which works in 32 bit mode, I could save presets (one in standard quality, another in maximum quality) and I tried theses presets with an app in 64 bits mode (Preview). I printed a photo twice, using the two presets. The printing with maximum quality was nice. So I could verify that the parameters of the presets were correctly handled when printing.

When the app works in 32 bits mode, I can print with all options. When the app is able to work in 64 bits mode, I have the choice :

- I can print while staying in 64 bits mode with the presets I save
- or I can quit the app, run it in 32 bits mode and then access to all the options for the printer.

I know, the S800 isn't a multifunction, but I think that the question is the same with multifunction printers. If the options are disabled, it's because they can't be accessed inside an app in 64 bits mode. Run it in 32 bits mode, or choose an app which only runs in 32 bits mode to prepare and save presets you'll be able to use in apps running in 64 bits mode.
