Which version of OS X are you running? I don't see the Deskjet 920c as a supported printer here -->> http://support.apple.com/kb/HT3669#HP.
Usually, on my Canon PIXMA MG8220, it's just a matter of setting up the printer to print in color mode in the Print dialog box.

Did it ever work in color with your present MacBook Pro and the operating system you are now running? Color cartridge good? The 920c is a very old printer and may not be supported by HP anymore.
