9.3.3 Installing and updating printer drivers
Printer drivers are software programs that allow the computer and printer to communicate. These programs also provide the user with an interface to configure the options of the printer. Every printer model has its own unique driver program. Printer manufacturers frequently update drivers to increase the performance of the printer, add new and improved printer options, and to address general compatibility issues. These drivers can be downloaded from the printer manufacturer website. The process of installing and updating a printer driver should follow the following steps:

Step 1
Determine the version of the installed printer driver
– All printer manufacturers use version numbers to uniquely identify print driver software. In general, the higher the version number of the printer driver software, the newer the version. It is important to know the version of the currently installed printer driver to ensure that it will not be replaced with an earlier version.

Step 2
Check to see if a newer, compatible driver is available
– Use a web browser to visit the printer manufacturer's website. The URL for the site is usually www.manufacturer_name.com. If this is not the case, use a search engine to find the manufacturer's site. Since driver updates are fairly common, most websites will have a link from the main page to the drivers (or support) page. Once the driver page is found and a newer version of the printer driver is located, be sure to research the printer driver to ensure that it is compatible with the computer's operating system. Compatibility issues include required operating system, system hardware specifications (such as RAM, hard driver space, and so on), application issues, and communication cabling.

Step 3
Download the driver
– Once the user determines that the driver is compatible with their system, it is time to download the printer driver file(s) to the local machine. Be sure to download all files that are necessary as well as any documentation for installing the newer software. These items should be downloaded and saved to a unique folder on the computer.

Step 4
Install the downloaded driver
– Installing the downloaded driver may be accomplished either automatically or manually. Most printer drivers are "packaged" with extra software that, when executed, will automatically search the system for an older driver and replace that driver with the new one. Manual printer driver installation is accomplished by navigating to the Printers folder in the Control Panel. Double-click the Printers folder, right-click on the desired printer, and click Properties. Depending on the OS, the name of the tab to click on will vary (Windows 98 is the Details tab, Windows 2000 is the Advanced tab). Click on New Driver and navigate to the location of the new driver.

Step 5
Test the newly installed printer driver
– The final step in updating a printer driver is to test the driver to ensure that it is working correctly. It is recommended that multiple tests be run to ensure compatibility. These tests should include using applications to print different types of documents, changing and trying out each printer option, and noting any problems that occur. If there are problems once the new driver software is installed, restart the computer and printer and run the tests again. If the problems still arise, contact the printer manufacturer or visit their website to report any bugs.
