Apple Software Update is a quick and easy software download method available directly through the Mac OS operating system.
You do not need to download a driver from HP Software & Driver Downloads if you install using Apple Software Update. This download method includes the HP print driver. Depending on your printer, the download might also include HP Utility, scanning software, and the HP fax driver.
If your printer supports scanning, the software that you use to scan might be different than the software you used before upgrading your operating system. Depending on your printer driver update, you can use Preview, Image Capture, or the Scan icon from the print queue to scan.
Additionally, HP recommends that you use this installation method in the following cases:
You no longer have the software CD that shipped with your printer
The updated full-feature HP software for the new version of Mac OS is not immediately available on the HP Software & Driver Downloads page
You updated Mac OS to a new version that released after your printer released
You are doing a first time install of a new version Mac OS on a new Mac
You already installed HP software on a Mac running an earlier version of Mac OS and have updated to a new version of Mac OS
