The Spool area is both the receiving area for jobs from users on the
network (Hold queue) and the waiting area for jobs that will be RIPped.
Hold queue jobs—When printing requires an operator (because
the Print queue and Direct connection are disabled), the operator
must assign a destination to all jobs received from users on the
network (icon 1 in the table above). Once assigned, jobs (icons 2,
3, and 4) move down the Spool queue for processing. All jobs
printed to the Hold queue require routing by an operator. The
Hold queue also enables you to use all workflow features of the
Command WorkStation with PDF files.
Print queue jobs—When printing does not require an operator,
network jobs sent to the Print queue appear in the Spool area,
where they are shown with a white printer icon (icon 2). When
they reach the head of the queue, they are RIPped and printed
without operator intervention.
Direct connection jobs—Jobs printed to the Direct connection are
not displayed in the Command WorkStation job lists. They are
displayed briefly in the status bars (where they cannot be
selected) and are included in the Job Log.
