ABSTRACT:
An information handling system projector tracks lamp usage to generate a lamp order form for order of a replacement lamp when lamp usage is a predetermined usage. The lamp order form is automatically generated and displayed to include lamp usage and projector identification information so that a user need not manually input that information into an order form. A network module of the projector supports queries for lamp usage from a lamp management module running on an information handling system. A projector processor interfaced with the network module reads the lamp usage and projector identification information from firmware of the projector and provides the lamp usage and projector identification information to the lamp management module for automatic generation of the lamp order form display.
