HP Printer Error 20 is caused by your HP printer not being correctly configured on your system. The error often occurs when you try and print a document on your system, and Windows discovers that it's not able to communicate with your printer correctly. Possible reasons for this error to emerge include the likes of having a damaged printer driver, incorrect printer settings on your system and the wrong settings on your PC. If you want to resolve this error, you need to be able to fix all the errors which cause it to show.



The error itself will often appear in this format:



* "Printer not activated - Error code 20″



In order to fix the HP error 20, you need to be able to repair the problems which first cause it to show. The various issues which lead to this error include the likes of the printer not being set as the default, printer drivers being missing and registry errors on your system.



The first step to fixing this error is to set the printer as the default printing device on your system. This can be done by clicking on Start > Printers & Faxes, locating the HP printer and then right-clicking on it. Select the "Set As Default" option for this printer, which should allow your computer to print from it. This is important because each time Windows wants to print something, it's continually having to open the printer that you want to print from. The only problem is that it's often the case that the "default" printer is not selected properly, leading your computer to get confused about the one it needs to print with.



The second step to fixing the error is to reinstall the driver & software for your printer. The driver & software for your printer are basically the files used to help Windows communicate with your printing device, and are extremely important if you want to print out anything on your system. In order to fix the printing error, you need to be sure that the printer is working as smoothly as possible, which should be done by reinstalling the driver it requires to run. To do this, you can download the driver from the HP website, and then completely uninstall the driver on your system. This will then allow you to install a fresh copy of the driver, which will be free or errors / corruptions.



The final step to fixing this error is to use a registry cleaner program to fix any potential errors that will be inside your computer. A registry cleaner is a very popular type of software tool that's been designed to fix a large number of errors on your PC. They basically work by scanning through your computer and fixing a number of potential errors that are inside your system, allowing your PC to run much faster and smoother. One of the big problems for HP Printers is that their drivers place a huge number of settings on your PC, which often get damaged or corrupted. If you want to fix the errors these software tools have, then it's recommended you use a registry cleaner to clean out all the issues on your system.
