Hi   @Mary-Wright-041,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand how  it can be when your printer refuses to come online, especially after you’ve already tried multiple fixes. 
Let’s work through this together step by step to get your HP Envy 6455e back up and running.

1.Confirm Printer Power

Ensure the printer is properly powered on and ready.

Check that the power cable is securely connected

Verify the printer’s display is lit and not showing error codes

If unresponsive, unplug for 30 seconds and reconnect

2.Check Wi-Fi Connection

Printers often go offline due to lost Wi-Fi connection.

On printer: Wireless button → Settings → Wi-Fi Setup Wizard

Make sure your printer is connected to the same Wi-Fi network as your computer

Re-enter Wi-Fi password if prompted

Restart your router and reconnect

3.Set Printer Online in Windows

Sometimes Windows marks the printer as offline even when connected.

Go to Control Panel → Devices and Printers

Right-click your HP Envy 6455e

Select See what’s printing

Click Printer → Use Printer Online

4.Update or Reinstall Drivers

Outdated or corrupted drivers can cause offline issues.

Visit HP Support → Drivers & Downloads

Download the latest drivers for HP Envy 6455e

Install updates and restart your computer

If issues persist, uninstall and reinstall the printer software

5.Run HP Smart App Diagnostic

HP Smart can automatically detect and fix connectivity issues.

Open HP Smart App → Printer Settings → Diagnose & Fix

Follow on-screen instructions

Apply recommended fixes

Confirm printer status changes to online
