Thanks for your further reply.

Unfortunately, I don't have access to the computer on which I'm trying to do this and have been trying to make things work by email.

However, I do have a copy of the relevant ppd file on my own computer. Almost at the end of it, there's the following line:
"*%CNPpdToOptKey CNInkCartridgeSettings --inkcartridgesettings".

It was in Canon's guide that I found the (correct) information that using the command "lpr <filename> -o CNInkCartridgeSettings=bk" would print the selected file in black only.

Would editing the line from the PPD file in the following way achieve what I want:
"*%CNPpdToOptKey CNInkCartridgeSettings --bk"?

Thanks again for your help.
