Empower your application with enhanced access to HP's TWAIN drivers  

Welcome to the HP Developers Portal website for the HP ScanJet and Digital Sender TWAIN SDKs.  Here you can obtain the solutions that will enable you to unleash the power of HP's scanners by tightly integrating our TWAIN drivers to your application.  The SDKs include drivers, documentation, and example code to get you started and easily tap into functionality that is not available through the standard TWAIN interface specification.

The SDK documentation includes sections on:

  • Understanding TWAIN
    • TWAIN specification
    • HP unique functionality
  • Instructions and use of example code
  • FAQ



The TWAIN SDKs are offered in two different categories: the TWAIN SDK itself and additional solutions that allow for access using different technologies (for example, .NET). These solutions are specifically for use with the Windows TWAIN driver.


TWAIN-compatible Application

The main solution includes drivers, documentation, and example code for using the HP ScanJet TWAIN drivers to their fullest capabilities. Read the Release notes for more details.


Other Solutions

Other solutions provide interfaces to the Windows TWAIN driver, such as .NET. The TWAIN driver is installed and together with the provided files, an API is provided for best integration.


To access and use the SDKs you will have to register for this site.  You will need to provide your information as well as the email of your HP contact.  Your request will be reviewed and you will be notified when you have access to this TWAIN SDK portal.
