Hi @The_World 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

It seems like your printer might be receiving and printing unintended network requests, often referred to as "RAW port 9100 jobs" or even spam print jobs. This can happen if the printer is exposed on your network and unintentionally accessible to external sources. 

Here are steps to prevent this and fix the issue:

1. Secure Your Network

Firewall Settings: Ensure that your network firewall blocks access to your printer from external connections. Only trusted devices should be able to send print jobs.

Close Port 9100: Port 9100 is often used for direct printing (RAW printing). If you don’t require this, disable it through your printer's settings or by configuring your router to block traffic on that port.

Go to the printer's settings, either through the HP Smart app or its Embedded Web Server (EWS). Locate the option to disable RAW (Port 9100) printing.

2. Use a Password-Protected Printer Setup

If your printer supports user authentication, enable it so that only authorized users can print.

Check the printer's Embedded Web Server (EWS) settings. You can access it by typing the printer's IP address into a web browser. Look for a section like "Security" and enable a password for administrative access.

 

3. Disable Unnecessary Features

Turn Off Direct Print Protocols:

Disable protocols like LPD, IPP, and RAW in your printer’s settings unless they are absolutely necessary.

Keep only the ones you use (e.g., AirPrint or HP Smart).

 

4. Update Firmware

HP regularly releases new firmware versions for printer enhancements, app updates, or issue fixes. Update the firmware regularly to get the most out of your printer.

5. Enable Private Printing Mode

Some HP printers support features like "Private Printing" or "Secure Printing," where print jobs are stored until a PIN or code is entered on the printer.

 

6. Restrict Printer’s Access

Assign a Static IP Address to your printer and limit access to it on the network.

Use MAC address filtering in your router to only allow trusted devices to interact with your printer.
