printer keeps alive without losing network access.īut on the corporate network, when the printer is on DHCP, it seems that it loses access to the network when the DHCP lease needs to be renewed (+/- 2 minutes) when a continuous ping is sent every 10 seconds (if no ping is sent, then it loses the network within 30minutes). I have the same with an M451dn (on a vast corporate network based on CISCO switches, with NAC & automatic VLAN assignation).Īs I don't have access to the switch configuration, even in ReadOnly, I'm not able to see how the duplex is defined, nor if the interface has errors counting increasing, nor if the spanning tree is flapping / is in blocking mode.īut what I'm sure of, if I place the printer in a simple test network (1 unmanaged switch, 1 firewall (LAN with DHCP + WAN for internet connection), 1 PC and my M451dn) everything is fine. It's an old thread, but did you succeed in resolving your printer issue? The above steps have worked on my home network of 3 computers. Close the windows clicking the Apply and OK buttons. I also clicked the checkbox, 'Always print to this device, even if its IP address changes'.Ĭlick Next, and the wizard completes. It matches the 'Host Name' shown when I request a 'Network Summary' report (from the printer's menu). It asks you to type in the Printer Name or IP Address: I entered that set of characters ('NPIB3379E') that was part of the printer name. Select Standard TCP/IP Port.(or HP Standard TCP/IP Port if shown)Ĭlick New Port. If WSD is checked, that is the problem! Adding a new port will un-check it.Ĭlick Add Port. Right-click the printer, select Printer Properties (NOT Properties). Mine shows up as 'NPIB3379E (HP Color LaserJet MFP M477fdw)'

(If not, the network printer needs to be added. Once you do one, it isn't difficult.Īssuming the printer shows up in the available printers.

You have to change the port on each Windows 10 unit. Here's what helped:įrom HP Customer Support: HP Printer Offline problem: How to fix. Hi KeithRObertson, I found this thread and your issues and what you described is the same problem I had.
