Logical destinations are objects in your InfoPrint Manager system that you can submit jobs to. In the simple print model shown in Basic print flow, the InfoPrint Manager environment has one default logical destination. You might want to add more logical destinations to support specific types of jobs and specific groups of job submitters. When you create an additional logical destination, you specify a name for the logical destination and associate it with a specific queue. The logical destination and the queue must reside in the same InfoPrint Manager server.
You can specify default job and document attributes for a logical destination, so that all jobs submitted to that logical destination are automatically assigned certain default values. This saves time for the job submitter, and helps make sure that jobs submitted will not fail because of missing resources. If necessary, the submitter can override the default values by explicitly setting the attributes at submission time.
Printer pooling (or clustering) is a powerful feature of InfoPrint Manager. Pooling allows jobs to be submitted to a single logical destination and then routed to appropriate physical devices. This feature enables you to distribute your work load evenly among available printing devices and to optimize printer utilization. It prevents bottlenecks where a large number of jobs are queued for a few printers while other equally capable printers sit idle. In short, printer pooling lets you see your output faster, and logical destinations make printer pooling possible.
