Hi @Riaan_Human,

Welcome to HP Support Community.  

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

If your HP Officejet 4500 printer is randomly printing out a sheet throughout the day without any prompt or command, there could be a few potential causes for this issue. Here are some troubleshooting steps to help you resolve the problem.

Check for Print Queue Issues:

• On your computer, check the print queue to see if there are any pending print jobs. Sometimes, a stuck print job can cause the printer to print repeatedly.
• If you find any pending print jobs, cancel them and check if the random printing issue stops.

Check for Viruses or Malware:

• Sometimes, malware or viruses can trigger unwanted printing. Run a comprehensive antivirus scan on your computer to ensure it's not infected.

Update Printer Drivers:

• Outdated or corrupted printer drivers can lead to unexpected printing issues. Visit the HP website and download the latest drivers for your Officejet 4500 printer.

Check for Firmware Updates:

• HP may release firmware updates to address known issues. Check the HP support website for firmware updates for your printer model and install them if available.

Power Cycle the Printer:

• Turn off the printer, unplug it from the power source, and wait for a few minutes. Then, plug it back in and turn it on. This can sometimes clear minor glitches.

Network Configuration:

• If the printer is connected to a network, ensure that it's not receiving print jobs from other devices unintentionally. Secure your network and printer settings to prevent unauthorized access.

Check for Physical Issues:

• Inspect the printer for any physical issues, such as debris or foreign objects inside the printer that might trigger random printing. Also, check for any loose cables or connections.

Factory Reset (as a last resort):

• If none of the above steps work, you can try performing a factory reset on your printer. This will reset all settings to their defaults, so make sure to note down any custom settings before doing this.

Remember to only perform a factory reset if you've exhausted all other options, as it will erase any customized settings you have on your printer.

I hope this helps. 
 

Take care and have a good day.

Also downloaded the HP print and scan doctor and it showed all good and up to date. Mystery printing continues.
