Print black/white (monochrome) with Canon under Ubuntu

Hey guys,

if you want to print monochrome with your Canon printer (in my case the mp495), you can do the following:

1. Open Printer
2. Select your printer, right click and choose properties
3. Go to job options
4. On the bottom there is a field where you type in "CNGrayscale" and hit add.
5. Now type behind your new entry CNGrayscale "TRUE" and click on apply.

That's it. If you want to print in color again, just change this entry to FALSE.
