Abstract

An automatic transmitting system for use in a networked printing system including a first client, second client and server. The automatic transmitting system includes an agent, operatively associated with the server, for maintaining information regarding a plurality of subsystems associated with a printing machine--the agent communicates with both the first and second clients. The automatic transmitting system further includes a registration system, including the first client, the second client and the agent, for registering the information. The information includes a first identifier and a second identifier, the first and second identifiers being stored with the agent and corresponded with first and second sets of information, respectively. In practice, the agent transmits the first set of information exclusively to the first client when a first event occurs in one or more of the plurality of subsystems and transmits a second set of information exclusively to the second client when a second event occurs in one or more of the plurality of subsystems.

Claims

1. In a network document processing system, a status reporting system using simple network management protocol ("SNMP") to report the occurrence of a selected event relative to the document processing system, comprising:

(a) a first SNMP unique identifier;

(b) an agent communicating with the network, the first SNMP being made accessible to said agent;

(c) a document processing server communicating with the network;

(d) a client communicating with the network, said client,

(i) registering at least an SNMP trap identifier with said agent, the SNMP trap identifier being associated with the selected event, and

(ii) transmitting a job written in a page description language ("PDL") to said document processing server, wherein a second SNMP unique identifier is embedded by said client in a PDL file representative of the job, and said server, upon receiving the job, extracts the second SNMP unique identifier from the PDL file representative of the job for storage in memory;

(e) in response to the occurrence of the selected event, said document processing server causes the first and second SNMP unique identifiers to be combined for forming the SNMP trap identifier; and

(f) in response to said combination, said agent transmits a copy of the SNMP trap identifier to said client for notifying said client of the occurrence of the selected event.

2. The network document processing system of claim 1, wherein the first SNMP unique identifier comprises a SNMP prefix object identifier and the second SNMP unique identifier comprises a SNMP suffix object identifier.

3. The network document processing system of claim 1, wherein said document processing server comprises a print server.

4. The network document processing system of claim 1, wherein the PDL file includes a comment section and the second SNMP unique identifier is embedded in the comment section.

5. The network document processing system of claim 1, in which said document processing server includes a document processing system process, wherein said document processing system process, in response to the occurrence of the selected event, causes the first SNMP unique identifier to be retrived for combination with the second SNMP unique identifier.
