We started getting an 81.09.00 embedded Jetdirect error on our printer. We have had the printer in a network environment for over a year and it was working fine. I called HP they did some initial troubleshooting which seemed to fix it that day but the next day we had the error again. I called HP again they sent a tech with a new formatter board. This seemed to fix the printer for about 1.5 weeks. I called HP again and they sent a replacement printer - this printer displayed the same error. I called hp again yesterday they sent a replacement printer today and this printer again is displaying the same error. We connected the printer to a laptop peer to peer - no error and it printed fine - HP says this indicates the Jetdirect card is not bad. We pull up a web page and navigate to the IP of the printer 169.x.x.xxx and I get a full page of options for the printer. We print from the web page no issues.
I connect the printer back to our network and get the error instantly. HP says its our network. I have tried new cables, new power cable, a different RJ45 port...even a different location in the office and the error persists. HP is putting the blame on our network. Although nothing has changed in the network, no AV/Firewall, no windows firewall, and all other network printers are printing fine configured with either a static IP or handed down through DHCP. Any help????
