my OfficeJet Pro 6978 is not printing in black

HP OfficeJet Pro 6978
macOS 10.14 Mojave

The printer was low on black ink.  I replaced the cartridge and it wouldn't print.  I put in another new HP black cartridge and still wouldn't print.  It will print color.  It will print copies.  I have done a hard re set per the recommendation and still no change.  Help??
