Printing greyscale

I believe you can use a greyscale color profile to use as the printer color profile for that specific print job. This will convert all colors to a greyscale, which will then be sent to the printer as such. In the print dialogue box you should have a menu with the program name on it (ie: TextEdit, if you're printing from that program). In this menu there should be a "Color Matching" option, with a few options. In there, select "ColorSync" and from the drop-down menu select "Other Profiles". Then either search for or locate the profile called "Generic Gray Profile" and click OK after selecting it.

With that profile selected, continue printing and the output should be grey. Optionally you can use the "Black and White" profile which will only output those two colors without a greyscale...

In Mail, when you open the print dialogue there's a popup that says 'Mail', select 'Paper Type/Quality' from that, then select 'Paper' as the heading to the next bit, there you'll find the 'Grayscale' option under 'Colour'.

When you select "Colorsync", are any options available to you? In the menu that initially has the name of the application you're printing from, the first set of options should be universal. The second set are printer driver-specific.

What driver are you using? If you're using the one given to you by Canon, you might try the built-in gnutenprint drivers instead. Most printers should have an option to print in color and greyscale built into the drivers.
