Group your printers into network groups to improve efficiency, security, and system performance. To assign a printer node to a network group, use the GROUP parameter on the NODE statement.
Business Value:
The group concept used in CA Spool has a major impact on system performance and system security. It is a best practice because groups are more efficient: shared, related printers are in logical groups; display of relevant files is easier based on groups; security is more efficient since access to resources is granted at a group level; and system performance is improved because printers and files are chained in groups. The use of network groups dramatically reduces the CPU overhead in big CA Spool systems with many printers and files.
Additional Considerations:
Full distributed user control is implemented through the concept of network groups. The grouping of printers into network groups is completely controlled by software, and the groups are not necessarily related to the physical location of the hardware. Similarly, no restrictions are imposed on hardware types.
Each printer node defined to CA Spool is assigned a network group number by the CA Spool administrator. The node definitions and the spool files directed to any of these printers form the logical entity of a network group.
The division of network nodes into network groups provides decentralization and security. In the network group, users are:
Users cannot see or access files and devices in another network group; they can, however, route their own files to destinations defined in other network groups.
When a user wants to display printers, the network group printer chain is used; it is not necessary to scan all printers in the system. In the same way, when a user wants to display files, the network group file-chain is used instead of scanning all files in the system.
