Conﬁguring Spoolers, Queues, and Logical Printers

Conﬁguring Logical Printers for Workload Balancing

The main advantage of the printer pool conﬁguration is that it balances

the workload of jobs submitted to the system. Jobs in Queue3 that can

print on both physical printers will print on the printer that becomes

available ﬁrst. Although PhyPrt4 is a high-speed printer compared to

PhyPrt3, if PhyPrt4 is busy for a long time processing a large job, some

medium size jobs do not have to wait but can print on PhyPrt3.

To create the logical printer LogPrt7, shown in Figure 6-8, “One Logical

Printer for Multiple Physical Printers,”, enter:

pdcreate -x “associated-queue=Queue3” Spool1:LogPrt7

This logical printer does not implement any restriction to the use of the

capabilities of the two physical printers associated with the logical

printer.

This example shows how to restrict the size of jobs at the physical

printer. Because the job-size-range-supported logical printer

attribute has no value, logical printer LogPrt7 accepts jobs of any size.

The spooler sends jobs that are relatively small to PhyPrt3 and sends

only large jobs to the high-speed physical printer PhyPrt4. Notice that

there is some overlap in the range of the sizes of jobs that the physical

printers accept. Based on job size, some jobs can be sent to either

physical printer, depending on which physical printer becomes available

ﬁrst.

The document-formats-supported logical printer attribute does not

have a value and, therefore, can accept documents with formats

supported by both physical printers.

You also can restrict with other attributes, such as

maximum-copies-supported.
