[sdfdesgf]

hi, I want to print black white without colour ink.

The faq only shows **bleep** info. my printer tells me the default error messare. What can I do?

THe **bleep**ed up support tells me there are some printers who can not do this, but not which model. I have a Office jetpro 7720

Welcome to the HP Support Community.

For your Printer, you wouldn't be able to do that. You would need the other three color inks.

Let me know if this helps.
