20 Most Recent HP DeskJet 6988 Printer Questions & Answers

Is the printer software installed on the laptops? Are you trying to print from the laptop itself, or a phone or tablet?

Try to use a smartphone and install the HP mobile printing app, if that app is able to find your printer, it is indeed on the network correctly. If you can print from the phone/tablet, but not the laptops, you need to install the software drivers for your printer to your laptop(s) you wish to print from.

I would take the cartridge out, and use a qtip with a bit of rubbing alcohol on it to clean off the contacts on both the cartridge, and the corresponding one on the printer itself. It seems as though the printer is unable to get a signal from the cartridge so it is just displaying a generic 'out of ink' error.
