Hi @afafsh,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

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

Try these steps:

Check USB Connection: Ensure that the USB cable is securely connected to both the printer and your computer. Try using a different USB cable or port to rule out any problems with the current cable.

Printer Drivers: Ensure that you have the correct printer drivers installed. You can download the latest drivers from the HP Support website.

Printer Status: The red light might indicate a specific error such as a paper jam, ink cartridge issue, or that a door is open. Check the printer's control panel for any specific error messages and resolve accordingly.

Restart Devices: Turn off the printer and your computer. Wait a few seconds, then turn them back on. This can resolve minor connectivity issues.

Software Update: Make sure your computer and HP Smart app are updated to the latest versions.

USB Settings: Ensure that your computer's USB ports are enabled in the BIOS settings.

I hope this helps.
