On HP Printer 7640--we can't print in color

[Singerlady]

All of a sudden we couldn't print in black.  We replaced the black cartridge and can print black, but now we can only print in black and not in color.  We have an HP Envy 7640 printer.  We have searched and search for answers.  I think the messaging

between the printer and the Mac computer is bad, but haven't been able to find a way to fix it.  I don't want to completely reset my  computer and printer.  I didn't do that for myself in the first place.  I don't want to get into the guts of setup.  I just want a button on my computer screen to fix it.  It has been over a week that we have been searching for a solution.  Something simple, please!
