How to change printing defaults to print "black/white"?

[Imola Ghost]

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.

Any ideas?
