One way to monitor a device, is to obtain a copy of the MIB or MIBs that the device supports. The MIB is part of the Simple Network Management Protocol (SMNP), and is used to obtain status about a device on a TCP/IP network. Managed objects are accessed a via virtual information store which is called a Management Information Base or MIB. Objects in the MIB are defined using the Abstract Syntax Notation One (ASN.1) The ASN.1 is an ASCII text file, written in a precise format that describes the management information available on a particular class of devices.
The Standard MIBs, which are freely available to all members of the Developer Support Website, provide basic information, name of equipment, speed, print status, paper sizes, configuration, etc.
