Repeating connectivity issues

[RustyYusuf]

Purchased a brand new HP OfficeJet 9120e and I have to reset my router, my Samsung Galaxy S20 Ultra 5G and my printer in order to possibly use it. It worked great the first few days and thereafter it doesn't allow printing from my phone. In the HP app, it shows the printer online and ready for use, but when I try to print, it shows a printing error and never completes. I'm ready to take it back to get a refund and purchase a different brand altogether. Added note; HP expects me to purchase a support package which I believe is an insult with my barely a month old purchase.

Welcome to the HP English Community --

Unless the "expects you to" translates to mandatory, the offer for any service is a matter of personal choice.

Yes, you should have a printer that meets your expectations.

We do not judge what people decide to do --

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

If you still have the printer...

If the issue is one of connection, you can check and adjust that setup using the Embedded Web Server (EWS) and your browser.

The printer would perhaps do better when connected with Ethernet to your network.

Printers in general do better, even on wireless, when the printer is assigned its own manual / static P address.

Printers of this type might do better when each of the frequencies supported on the router are designated with separate SSID named networks for each frequency (band) and the printer is connected to the SSID named network you expect it to use.

Initial connection to the printer during setup requires the phone's Bluetooth and Location services to be switched ON .

If you have lost connection and must start over, keep that in mind,.

If you are using HP Smart, make sure that VPN is switched off at least during initial connection.

I cannot verify that VPN would work even after that point.

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A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.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

If your router supports it, create a separate SSID named network for each frequency.

Connect the printer to the SSID network you want the printer to use on the network.

Wireless

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

Examples – EWS Setup – IPv4

EWS > HP Document / How-to (original format)

Use the HP printer Embedded Web Server (EWS)

NOTE:  Find printer IP address

Section Open the EWS over a local network orientation

Ethernet

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

Tab Network > Wired (802.3) > IPv4 Configuration

Wireless

Original / Standard EWS format for HP InkJet Printers

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

Tab Network > Wireless (802.11) > IPv4 Configuration

If / As available on your printer:

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.

Newer / Select Printers - Alternate EWS format

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

Section Network > Primary Ethernet > Check / Adjust Status and other tabs...

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

Section Network > Wi-Fi > Section IP Config > IPv4

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

Example - EWS - Wireless - IPv4
