Hp Printers keep going 'Offline'

Brian1

I am using a USG60W firewall router and HP printers here. I have reserved an ip for the printer on the router and I can install the hp drivers and connect to the printer initially just fine. After about a week or so the printer appears 'Offline' and cannot print to it. I am not connected to the guest network, the printer is not either. The last few times this happened, I was able to remove the printer via the control panel and re-add it. Now when I go to re-add the printer it says it cannot find it on the network. 

I am able to ping the printer, the printer also shows it is connected to the network. 

Any suggestions ? Is this something to do with the firewall/ a setting within it? I have these printers at a different client location and never had this issue, the only difference is the Zxyel firewall router.

Would you please report...

LAN1 subnet

Printer subnet

Client subnet

Firewall rules among the subnets/segments...

I doubt it is a firewall issue if your PC is on the same subnet as the printer.

Assuming you are using Windows, my guess is the printer is being auto-added using a WSD printer port which in my experience is notoriously unreliable. Can you try to remove and re-add it again by IP address?

In Settings('modern' control panel), click 'Devices' then click 'Printers and Scanners'. On the Printers and Scanners page, click 'The printer I want is not listed'. In the 'Add Printer' window that appears, choose TCP/IP device, then type the IP of the printer and click Next thru the wizard.Installing it this way will force it to print to the printers IP instead of the WSD port.

@gb5102 That is the method I used to re add it after the initial install. That was working temporarily but would still end up getting the 'printer offline' issue after a week or so. Now when I go to re-add by the IP address, I get the popup that it cannot find my printer on the network. Again, I can still ping the printer and I can pull up the printer web page and see the status as 'connected'

Client computers and printers on the lan1 subnet, I can double check/see that through the wizard.

Is your TCP/IP Port on Windows SNMP enabled?

If the PC and Printer are in the same subnet, the traffic seems will not be managed by Firewall.
To investigate further, during the issue occur, can you private message the packet which collected on the firewall's Lan?
