Device State
each device. When the header message is turned on, it prints on the first page of the
job; the report name and location are printed in large banner-sized letters. If the
header message is turned off, jobs print consecutively with only a form feed (new
page) to indicate the beginning of the next job.
If you specify a batch header, the job information prints on two of the three trailer
pages as well as on the first two pages of each job. The trailer pages have printing
over the page folds, enabling jobs printed on accordion-fold paper to be separated
easily. The two-page header message always appears on the top page, regardless of
how the job is folded.
The actual header message produced depends on the print process controlling the
device. The headers described above are produced by the HP print process. If a
device is controlled by a user-written print process, the process can produce almost
any kind of header or none at all.
Device State
The device state describes the status of the device. There are six possible device
states:
Selection Algorithm
The spooler maintains a queue for each device (that is, a list of the jobs to be printed
on that device.) The job at the head of the queue is the next job to be printed.
As a rule, higher-priority jobs print sooner than lower-priority jobs. However, the
selection algorithm affects the order in which jobs print within the same priority level. If
the selection algorithm is FIFO (first in, first out) ON, jobs are placed at the end of the
queue and are printed in order. If the selection algorithm is FIFO OFF, the spooler
allows short jobs to print before longer jobs of the same priority.
PRINTING The device is currently printing a job.
WAITING The device is idle and is waiting for a job to print.
OFFLINE The device is not available for printing.
SUSPENDED The device is in the process of printing a job but has been
suspended by the operator (to change ribbons, for
example).
DEVERROR The device has produced a file-system error while printing.
Operator intervention is required.
PROCERROR The supervisor process has determined that the print
process for the device is not working correctly. Operator
intervention is required.
