Conﬁguring Spoolers, Queues, and Logical Printers

Creating and Conﬁguring Queues

HPDPS queues receive jobs from the spooler and manage the jobs until

the spooler schedules them to physical printers.

You can create and start a queue from SAM or from the command line.

Creating a Queue

To create the queue Queue1 contained in spooler Spool1, enter:

pdcreate -c queue Spool1:Queue1

Specifying the Queue Scheduling Method

HPDPS determines the position of jobs in the queue by the order that the

jobs were submitted and the scheduling method of the queue. When jobs

print depends on their position in the queue relative to other jobs; for

conﬁgurations with multiple physical printers, it also depends on when a

particular printer becomes available.

Use the scheduler-ready attribute to specify a scheduling method for

the queue. Supported values are fifo and priority-fifo with a

default value of priority-fifo.

To change the queue scheduling method for the queue Queue1 to fifo,

enter:

pdset -c queue -x “scheduler-ready=fifo” Queue1

Alternatively, you can set the queue scheduling method when you create

the queue:

pdcreate -c queue -x “scheduler-ready=fifo” Spool1:Queue1

About the First-In-First-Out (FIFO) Scheduling Method

The ﬁrst-in-ﬁrst-out (FIFO) scheduling method means that if several

jobs are waiting in the queue and all of the jobs can be scheduled to only

one physical printer associated with the queue, the spooler schedules the

jobs in the order in which the queue received the jobs.

Figure 6-1, “FIFO Queue Feeding Two Physical Printers,” illustrates the

fifo scheduling method. The number in parenthesis under each job

identiﬁes the physical printer to which the spooler can schedule the job;
