Discovery
Before Dell OpenManage Printer Essentials (OMPE) can manage network
printers, it needs to discover the printers on the network. OMPE detects and
identifies all printers connected to a network based on their IP address. After
discovery, the printers are automatically placed in predefined groups and
displayed in the printer status list. The details of all discovered printers are
stored in OMPE database.
OMPE discovers printers using Simple Network Management Protocol (SNMP)
on IPv4 Local Area Network (LAN). All printers that comply with RFC3805, 1213
and 2790 standards
1
are discovered by OMPE.
OMPE is capable of discovering printers in various modes either immediately or
scheduled for a later time. The various discovery modes available are briefed in
the table below:
1. Request for Comments (RFC) is a type of publication from the Internet Engineering Task
Force (IETF) and the Internet Society that defines methods and behavior of internet con-
nected systems.
Discovery mode Description
Local subnet
mode
Discovers all printers within the local subnet.
Single IP mode Discovers printers in a specified IP address. It
is the fastest mode to discover a single
printer and is suitable when a new printer is
commissioned.
IP range mode Discovers printers in a specified IP range.
This mode is useful for initial discovery of
printers in a large network. It is recom-
mended to run this during off peak hours,
since it is time consuming.
