Anything you can do to save space and lesson congestion on your computer is good. So it makes perfect sense to delete an unused USB (Universal Serial Bus) printer port when it is no longer required. Also, typically, the "Port/Description/Printer" list box contains room to view up to eight printer ports. To see the remaining ones, you have to scroll down. That's enough incentive to remove those outdated ports: You save a few seconds in scrolling and therefore locate the printer port you need much faster if you need to troubleshoot it.
Unplug the USB printer from the computer.

Click "Start" and then click the "Control Panel."
Select "Printers and Other Hardware."
Select the printer with the USB port that you would like to remove.

Go to the "Ports" tab and then highlight the USB port.
Click "Delete Port" and then click "Apply" and then "OK."
To delete several USB ports at the same time, first follow steps 1 through 3. Then in Step 4, after you highlight the first USB port, press and hold down the SHIFT key. Next, click the last USB port you would like to delete to select them, and follow through with steps 5 through 7.
These steps apply to Windows XP. However, as long as you know how to access your computer's printers' properties, you can delete all of the USB ports that you need. Visit Microsoft's website for more information.
