You can always set the option in the printer. I also don't have that option in the computer. I'm not sure why. Perhaps someone else in the forum can disclose the secret?
Hey CubaMark and Chas_m, where are you!
For my Canon bubblejet, there is an option on the print dialog box.
Get to the ColourSync dropdown and there's another dropdown for Quartz filter, and in there is a black & white filter (and a greyscale filter).
I think that will force it to print out using just black ink.
IIRC things like colour settings are provided by the printer drivers, and I can see where the manufacturers would want to force you to waste a lot of colour ink so they can sell more cartridges...
She who laughs last -- probably made a back-up.
Sharonmac09 - I cant find any reference to the printer other than in System Prefs > printer and in Print when I go to print something. My printer shows up there but there's nothing there to let me change from colour to b&w. Is there another place where I'd find printer info?
This printer was on my PC til I got my Mac. I was able to go into setting there and change what I wanted to change, but I dont see it on here.
