Hi @crommy ,

Welcome to The HP Support Community.  

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

I understand you're encountering a Code -900 error when trying to use your HP ENVY Pro 6455 All-in-One Printer with your HP Chromebook, and the printer isn't being recognized on the network. Here are a few steps to troubleshoot this issue:

Ensure Both Devices Are on the Same Network:

• Double-check that your HP ENVY 6455 printer and your Chromebook are connected to the same Wi-Fi network.

Restart Devices:

• Power off your printer, Chromebook, and router.
• Wait for about 30 seconds, then power them back on in this order: router, printer, and finally Chromebook.

Check Printer Connection:

• On your printer’s control panel, verify that it is connected to your Wi-Fi network. You may need to run a network diagnostic or print a network configuration page from the printer settings.

Update Printer Firmware:

• Check if there’s a firmware update available for your printer. If you can access the printer's settings, look for an update option, or visit HP’s support page to download the latest firmware.

Check HP Print for Chrome:

• Ensure you have the HP Print for Chrome extension installed on your Chromebook. You can download it from the Chrome Web Store. This extension helps connect your printer to the Chromebook.

Reinstall Printer on Chromebook:

• Remove the printer from your Chromebook settings, and then re-add it by going to Settings > Advanced > Printing > Printers > Add a printer. Select your printer from the list, and it should automatically reconnect.

Reset the Printer's Network Settings (if necessary):

• You may need to reset the printer's Wi-Fi settings and reconnect it to the network. This can typically be done from the printer’s control panel under network settings.

Let me know if you still encounter issues after trying these steps!

I hope this helps. 

Take care and have a good day.
