Hi @Tina6531,

Welcome to the HP Support Community.
 

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

Sure! Ports (COM & LPT) in Windows 11 refer to serial (COM) and parallel (LPT) ports, which are used for connecting legacy devices like printers, scanners, and industrial hardware. Here’s how you can manage them:

View and Configure COM & LPT Ports in Windows 11

1. Open Device Manager
   • Press Win + X → select Device Manager.
   • Expand Ports (COM & LPT). You’ll see entries like: 
     • Communications Port (COM1)
     • Printer Port (LPT1)
        
2. Change COM Port Number
   • Right-click the COM port → Properties.
   • Go to Port Settings → Advanced.
   • Under COM Port Number, choose a different port if needed (e.g., COM3, COM4).
      
3. Enable Legacy Ports
   • If you don’t see COM & LPT ports, they might be disabled in BIOS.
   • Restart your PC → enter BIOS → enable Serial Port or Parallel Port.
      
4. Install Drivers
   • For USB-to-Serial adapters or older printers, install the correct driver from the manufacturer or Windows Update.

I hope this helps.

Take care and have an amazing day!
