W11 HP printer seems to keep changing the printer port so printer stops working

[Gene2023]

We have a HP 9015 OfficeJet printer. I have assigned it the IP 192.167.0.200 on the printer.  We have a desktop and two W11 laptops. Randomly both the laptops are unable to print and when I check, the print SW on W11 is no longer pointing to the IP I assigned. Once I change it back, it seems to work fine until next time. Why and what is changing the port on the printer?

Welcome to the HP Community --

Offline Condition

Although the printer appears to be switched on, it does not communicate with other devices on your network.

Consider >> Restart All

Restart Everything, including the router that controls your network

What else?

============================

Odd IP Address Assignments

One thing that might cause a similar type of oddity is a conflict on the router in the assignment of the IP addresses.

What?  In the simpler scenario, if two devices are inadvertently assigned the same IP address , if the first device is quiescent (idle), the second device to come online (when detected by the router) can knock the first device off the network.  True -- there would generally be entries in the router logs.

Another, much less common occurrence also involves the router and a mis-matched IP / Mac Address pair.   What?  This can happen if you replace a printer on your network with a different printer and use the same IP address on the "new" printer as was assigned to the original printer.  The router, if it does not clear the original printer's IP / Mac address pair entry, cannot connect the replacement device.  True -- this type of conflict generally keeps the printer from connecting at all.  Check the router logs and the IP address assignments for static / manual settings.

============================

TCP/IP Connection

-------------------- --------------------

Method – Windows - Add printer using TCP/IP

Try adding the printer using the printer’s IP address

Find the IP Address of the printer on the Printer Control / Display Panel (touch Wireless button)

Control Panel > icon view Devices and Printers

Click in the top ribbon, Add a Printer

Wait till the menu starts…
Select / Click The printer that I want isn’t listed
Select / Click Add a printer using a TCP/IP address or hostname

Select / Click Next
Device Type > Select in Drop-Down Menu: TCP/IP Device

Hostname or IP Address > Enter the IP Address of the printer

(Skip Port Name)

Select / Click Next

Complete any additional information

-------------------- --------------------

Method – Windows - Create TCP IP port (InkJet Printer) - Change connection type

Method - Create / Change-to TCP/IP port

TCP/IP can resolve odd connection, scanning, and installation problems.

Create / Switch to a TCP/IP Port to facilitate communication and prevent ‘offline’ issues

Find the printer's IPv4 address

Print a Configuration Page

OR

Tap on the wireless icon on the Front panel of your Printer to get the IP address

Next,

Windows 11

Settings > Bluetooth & devices > Printers & scanners > Select Printer > Printer Properties

OR
Control Panel > icon view > Devices and Printers > Right-Click the printer > Left-Click Printer Properties

Tab Ports
Click Add Port

Select Standard TCP/IP Port

Select New Port and follow the instructions
Type in the correct IP address for the printer

Printer - Dual Band Network

Less likely just because you likely know your network and how the SSID named networks are set up.

Dual Band Network - Considerations

Reminders 

Do not ignore your router --

A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.

If the printer supports it, connecting using Ethernet is generally a better choice.

Some printers, particularly older models, only support Wireless at 2.4GHz

Some printers support Wireless at both 5GHz and 2.4GHz – but not at the same time

Regardless, if the printer won't work or cannot connect to your 5GHz SSID named network, connect to the 2.4GHz network.

If you are running a Dual Band Network,

 Check that the router is set up to broadcast all frequencies it supports.

Next,

If your router supports it,

On your router:

 Create a separate SSID named network for each frequency supported by the router

 What?  Create one SSID named network for 5GHz and one SSID named network for 2.4GHz

and

 Connect the printer to the SSID named network on the frequency / band you want it to use.

In general,

• 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
• 5GHz is faster

EWS – IPv4 - Check / Adjust the printer connection - SSID named network

Manual IP Address

EWS > HP Document / How-to

Use the HP printer Embedded Web Server (EWS)

NOTE:  Find printer IP address

Section How do I manually assign an IP address to my printer?  Items 1-2

Ethernet

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wired (802.3) > IPv4 Configuration

Wireless

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wireless (802.11) > IPv4 Configuration

As Available:

Tab Network > Wireless (802.11) > Advanced

Network Interface on / off, Network SSID name, Security Settings, Passphrase / Password

Select and connect to the correct SSID / network name for the bandwidth you are using.

Note:   It is not mandatory that you use a manual / static IP address.  Doing so can improve stability.

Just to add another simple solution: On the printer, through the embedded web server, disable WSD print. The challenge you are likely having is that Microsoft is like the petulant child who knows everything and insists that all games are played by their rules.

I restored the factory settings on the printer and it seems to be working now. 

Thanks for your comments.

@Gene2023 

You are welcome.

Factory reset is sometimes the only path to restore the balance.

Happy Printing.
