The device layer, or HP OXPd, provides a software development kit (SDK) for creating document workflow applications based on standard web service protocols.
HP OXPd version 1.6 provides a development platform for creating web applications that improve document workflows.
These web applications, called document workflow applications, typically reside on remote web servers and users access them via the device control panel of an HP LaserJet MFP or HP LaserJet Flow MFP.
From a developer's perspective, the HP OXPd enabled device is a server component which provides access to the exposed methods via the SOAP protocol.
When users press the menu button a browser application is launched and the URL is retrieved from the remote web server and displayed on the device control panel.
Users interact with the remote web application via a dynamically rich touch-based graphical control panel.
Scan job tickets contain important information like destination (http) and filename, optional metadata, and transmission mode.
The HP OXPd enabled device will request and validate a server’s identity certificate before establishing a connection.
This security measure will encrypt the users' credentials and effectively protects sensitive data travelling to and from devices from unauthorized access.
