Hardware :: Change Printing Defaults To Print "black / White"?

I don't print much full color and when I do print I'd like to back off of the higher quality printing to save on ink. Does anyone know how to change the default to print a rough draft [and save some ink] rather than printing using a lot of black ink? Also, I cannot print in MS Word. I can print anywhere else, like stickies or whatever. However, my wife [on her account] can print everywhere even in MS Word.

I get an error message saying: Word could not communicate with the printer. There are several possible reasons: *Your printer or its driver may not be set up correctly or there may be a problems with the network connection. You may need to adjust your printer settings. *There may be a bad connection between your computer and printer. Like I said my wife and I share this 27" iMac and she can print fine on her account but I cannot print using MS Word.
