HP Scanjet scanners have an ICA driver to enable scanning with Apple's Image Capture application in OS X El Capitan (10.11), OS X Yosemite (10.10), and OS X Mavericks (10.9). Use this document to find out which Scanjets have drivers available.
note:The HP ScanJet Professional 1000 and 3000 models do not have a ICA driver available and do not support the Apple Image Capture application. Go www.hp.com/go/support to download the HP scan software for Mac.
note:As a best practice, HP recommends that this setting be set to ‘Mac App Store and identified developers.
