The easiest way to troubleshoot an HP printer is to use the HP Print and Scan Doctor to diagnose and fix problems. This software can be downloaded from the HP website and automatically fixes many common problems with HP printers.
If the HP Print and Scan Doctor software cannot find or resolve a problem, there are additional troubleshooting steps. The first is to make sure the printer's driver is up-to-date. HP provides HP Printer Install Wizard software, which automatically searches for the latest drivers and installs them. This software may not work if the printer can't connect to the network, so a manual driver update may be required.
If updating the printer's driver doesn't work, the next step is to search for the problem manually. The HP Support website contains a number of documents on how to troubleshoot common problems, such as a printer losing network connections or print jobs becoming stuck in the queue. These support documents contain step-by-step instructions on how to solve many possible scenarios.
The HP Print and Scan Doctor software is only available for Windows and doesn't work on other operating systems such as Mac OS X. For these operating systems, the user should manually troubleshoot the problem using the HP Support documents.
