14 Introduction
The OMPM architecture diagram illustrates the communication between various components (portal
and OMPM engine) and printers in a network.
The portal is an interface that displays information about the printers. The portal and the OMPM
engine communicate using Hypertext Transfer Protocol (HTTP).
OMPM uses Simple Network Management Protocol (SNMP) to discover printers in a network. SNMP
and HTTP are used to communicate with the printers to collect printer data and to get or set the
device parameters.
The OMPM engine is connected to databases that manage information about users, configuration,
grouping, discovery, health status of a printer, and other related parameters and store information about
configuration, templates, traps, discovered devices, health status, and printer status values.
