Man, I'm embarassed asking this question, but I just can't see how to do it. I have a Deskjet printer, but my colour cartridge is empty and I need to print out a document this afternoon. Of course, printing it from Safari defaults to colour meaning a lot of the info is a really faint grey colour, or just non-existent. I've downloaded the latest printing center from HP but the Toolbox option just lets me do diagnostics. In page setup when printing, there's just the usual paper size options. Am I missing something really obvious?!?! Its driving me mad! Thanks, Mike.
