DeskJet 6940: ethernet connection between the new modem and printer does not transmit Mac

I just installed a new modem to Qwest; It works wirelessly with my iMac 10.11. My old (but functional until yesterday) Deskjet 6940 is connected to the modem via Ethernet. When I try to print, the document seems to be transmitted to the printer, but then it hangs on and I get the message "the printer is not connected" - which it is, plugged, ethernetted, and set in motion. Support of Qwest says that only 10% of the info from the computer are the printer, but he seems to think that the part of the new modem Ethernet is functional,

I have already tried all unplug/restart/send/add printer new check/updates / IP (cannot connect) / ethernet ports and cables, etc.

Any other ideas?

Thank you!

Hi @newgranny,

Thanks for getting back to me.

It is good that the printer has been able to print a diagnostic page.

Ensure that the router and firewall on the market do not block these ports.

Ports of printing:

  • UDP ports: 427, 137, 161
  • TCP port: 9100

Card photo upload:

  • UDP ports: 137, 138, 427
  • TCP port: 139

The HP device status:

  • UDP port: 161

Ports of Web Services:

  • UDP and TCP: 80, 443, 5222 and 5223

Hello Ports:

  • TCP and UDP: 5353 and 5297, 5298

Unplug the wired network (ethernet cable), restore the default values on the printer.

Restore the default settings.

Follow these steps to reset the printer to factory default settings:

1. check that the printer is on.

2. press and hold down the button to report Page.

3 while holding down three times the homepage button, press the Cancel button.

4. release the report Page button.

  • Restart the printer.
  • Connect the ethernet cable.
  • What were the results?

If the problem persists, try the USB connection.

Please reply to this message with the results. Good luck!
