Hi @rdnash,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you’re having trouble with your HP MFP M278-M281 series printer going offline and having issues reconnecting to your network. Here’s a step-by-step guide to troubleshoot the issue and find out how to get paid support if needed:

Troubleshooting Steps

Check Printer Network Settings:

• Printer Control Panel: Go to the printer’s control panel and navigate to the network settings. Verify that the printer is connected to the correct network.
• Reconnect Printer to Network:
  1. On the printer’s control panel, go to Setup or Network Setup.
  2. Select Wireless Setup Wizard and follow the prompts to reconnect to your Wi-Fi network. Make sure you enter the correct passkey.

Verify Network Connection:

• Router Settings: Ensure that your router is working correctly and that other devices are able to connect to the internet.
• IP Address Conflict: Check if there is an IP address conflict. You can print a network configuration page from the printer’s control panel to see the IP address and check if it matches any other device on the network.

Update Printer Firmware:

• Check for Updates: Sometimes, outdated firmware can cause connectivity issues. Check HP’s website for any available firmware updates for your printer model and install them.

Reinstall Printer Driver:

• Remove and Re-add Printer:
  1. On your computer, go to Control Panel > Devices and Printers.
  2. Remove the printer from the list.
  3. Go to Add a Printer and follow the prompts to add the printer back.
• Download Latest Drivers: Ensure you have the latest printer drivers from the HP Support Website.

Check for Firewall or Antivirus Issues:

• Temporarily Disable Security Software: Sometimes, firewall or antivirus settings can block network communication. Temporarily disable these and see if it resolves the issue.

I hope this helps.

Take care and have a good day.
