How to Fix HP Printer Code 20 on Your Windows System

HP Printer Error 20 can be one of the most common errors in Windows printers. This error is caused by your HP printer not being configured correctly, causing Windows to become unable to use it properly. This error is quite common and easy to fix if you can find a way to correct the problems that caused it.

The error message that you see often looks like this:

“Printer not activated – Error code 20″

This error will disappear if you make sure your HP Printer works on your computer. You will need to make sure your printer is connected to your computer, that the driver is installed and that the default printer has been set.

You must make sure your HP printer is the “default printer” for your PC. This printer may not be the default and Windows will not be able to print anything. To set this printer as default, click onto Start > Control Panel > Printers & Faxes and then right-click your HP printer & set it as default. The error might not show, but it may.

You will then need to install the driver for “USB Composite device” on your system. This is the technical title of the USB port to which your Printer may be connected. After reinstalling it, Windows should be able to read any files it needs. Simply open the “Device Manager” on your computer and choose the USB composite device. Allow it to be removed and then let it install again.

Final, clean up the registry to make sure there are no broken parts that could be causing the HP Error Code 20. The registry is a large internal database that Windows uses to store all the files, settings & information it requires to run, and is a very important part of your system. The registry is constantly corrupted or damaged, which can cause many errors, including error 20, This can be fixed by using a registry cleaner that scans the database and repairs any errors.
