3.2 Glossary
HP EC: HP Embedded Capture (HP EC) is embedded software that is installed on devices. Highly customizable,
the HP Embedded Capture solution integrates tightly into customer backend processes and applications,
enabling serverless and decentralized document capture from HP devices.
TWAIN: A standard software protocol and an (API) that regulates communication between software
applications and imaging devices, such as scanners and digital cameras.
3.3 Components around HP Embedded Capture (HP EC) TWAIN
solution
The main components of HP Embedded Capture TWAIN are the TWAIN driver (running on client PC) and the HP
Embedded Capture software (running on the HP Multifunctional devices): a TWAIN-enabled application
interacts with the TWAIN driver when submitting a scan request. Later, the HP Embedded Capture software
manages the scan process in the devices and, once the images are available, can be inserted directly into the
TWAIN-enabled application, or saved for future use.
HP Embedded Capture TWAIN components:
●
TWAIN compatible application: TWAIN-enabled application used by the customer to fire scan jobs and
get back digitalized images (Microsoft Clip Organizer, IrfanView, Twain Twacker, etc)
●
TWAIN driver: Provides TWAIN interface to the Customer application. Supports all mandatory
operations and capabilities as defined by TWAIN specifications.
●
HP Embedded Capture (HP EC): Embedded component interacting with device firmware that manages
the scanning process.
