Foreign Interface Harness
Abbreviated as FIH, Foreign Interface Harness is a port that enables Hewlett-Packard (HP) multifunction printers (MFP) to use third party devices to extend the capabilities of the MFP. Using the FIH with third-party equipment allows you to track information about copies produced on an HP Digital Copy module. Additionally the FIH can also expand the MFP capabilities by adding additional fonts, forms, barcode printing, and other features. To use the FIH you first have to install the FIH software for compatible MFPs.
