Apple has released a large number of printer updates for OS X systems, so if you have a printer configured with your system, you may see an update available in Apple's Software Update utility.
The updates are specifically for devices from Canon, Epson, Lexmark, Infotec, Gestenter, Ricoh, Savin, Lanier, InfoPrint, and NRG.
While Apple makes these driver updates available for download from its Support Web site, the installation packages include all the drivers from a specific manufacturer, and installing them all will be overkill for most home users. While in some cases the driver packages are only a few megabytes in size, in other cases they are at least a few hundred megabytes. Therefore, instead of downloading and installing the entire driver set, it may be best to rely on Software Upate to supply you with the necessary driver update.
As with any software updates, be sure to fully back up your system before applying this update. While often printer driver update issues can be corrected by resetting the print system or otherwise uninstalling and reinstalling your printer, there is always the possibility of an update resulting in larger issues.
