printer offline

[bear1066]

Greetings.  Once again, my fancy, all in one plan, 9129e all in one printer is "offline" and after an hour and a half remains offline.  All of the easy answers (turning everything off and on, wi fi connections to the both the HP computer and the HP are excellent, etc) have failed.  The last time I had this problem it was a two hour adventure with a support person to fix it.    And no, HP Smart (a generally useless program to begin with), and its diagnosis and fix program, doesn't help--it "can't find" my printer (it's on the desk if that helps any).   It's probably something obvious that I'm missing and any advice is appreciated.  If I say anything more, I'll just get myself into trouble so I'm quitting for the evening.

I should have mentioned that I attempted to connect via IP address, printer still couldn't be found, then went to update software, same problem (although this time, even though the correct IP address (taken directly from WI FI network test results) was used, I was told to "use the correct IP address."

And I removed the device thinking I could perhaps just add it, but no such luck.  I was told device (which was on, fully connected to wi fi, copies, scans, etc, just won't connect to the HP computer) wasn't listed, and then went through the IP circus again, no soap.

Hi @bear1066,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding offline issues with the HP OfficeJet Pro 9129e printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Restart Devices:

• Ensure that both your printer and computer are turned off.
• Turn your router off and back on to refresh the network connection.
• After a few moments, turn your printer and computer back on.

Check for Connectivity Issues:

• Make sure the printer is connected to the same network as your computer or mobile device.
• Verify the wireless signal using the HP Smart app or printer display. A steady blue light generally indicates a connection.

Verify Printer Online Status:

• Go to your printer settings:
  • Windows 11: Click Start > Settings > Devices > Printers & Scanners.
  • Right-click your printer and make sure "Use Printer Online" is selected if it appears as offline.

Run HP Print and Scan Doctor:

• Download and run the HP Print and Scan Doctor tool to automatically diagnose and fix any printing issues.

Reinstall Printer Drivers:

• Uninstall the printer from your system and then reinstall it using the HP website to ensure you have up-to-date drivers.

Default Printer Settings:

• Ensure the correct printer is set as the default printer on your computer.
• In the Printers & Scanners menu, the default printer will have a check mark next to it. Make sure the HP OfficeJet Pro 9129e is set as default.

Firewall or Antivirus Software:

• Sometimes, these can block connection to your printer. Temporarily disabling could help restore the connection.

Network Configuration:

• Print a network configuration page from the printer display to verify its IP address and other network settings.

I hope this helps.

I'm not entirely sure, but I think what worked here was reinstalling the print drivers--it wasn't exactly a clean experiment as I was attempting several different ways of addressing this problem at the same time.  I've had this problem three times in the last two months or so that I have had this (allegedly) high end 9129e printer, and at least two of those were after I turned the printer off because we were going to be away for a couple of days.  We simply won't turn it off, absent very long absences, and maybe that workaround will prevent repeat adventures along this line.  HP Scan also was disabled and I don't have thiat working yet--but I'll try a couple more alternatives before seeking additional help.  We can limp along with HP Smart for a little while as I do this.  There are some software issues here that need attention from people a lot smarter than me.

I'm grateful for the advice, though--I think it helped.
