VueScan works with the Hewlett-Packard ScanJet 4070 on Windows and Mac OS X.
You need to install an HP scanner driver to use this scanner on Windows and Mac OS X.
If there isn't an HP scanner driver at www.hp.com for your operating system, then unfortunately VueScan won't work with this scanner. VueScan uses a plugin library that's installed with the HP scanner drivers to talk to this scanner, and doesn't work with this scanner without this plugin library.
On Windows x64, you need to use VueScan x32 to use this scanner's transparency adapter.
This scanner is supported on Mac OS X Lion and later if you first install the HP scanner drivers.
If you have an iPad, iPhone, Android phone/tablet or Kindle Fire, you can use VueScan Mobile with WiFi scanners or the built-in camera to scan documents.
