Printer Attributes
Each printer (and associated print process) on your system has these attributes that affect
your spooler jobs:
Form Name
The form name of a printer defines the type of job that can be printed on it. Only a job
whose form name is the same as the form name of the printer can be printed. For an
example, see
Job Form Name
Header Message
The header message includes the job report name, location, job number, form name, and
date and time of printing. An operator can turn on or off the header message for each
printer. When the header message is on, it prints on the first page of the job; the report
name and location are printed in large letters (see
off, jobs print consecutively with only a form feed (new page) to indicate the beginning
of the next job.
If the system operator specifies 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 easily
separated. The two-page header message always appears on the top page, regardless of
how the job is folded.
The actual header message depends on the print process controlling the printer. The
headers described above are produced by a NonStop™ Kernel print process. If a printer
is controlled by a user-written print process, it can produce a custom header (or none at
all).
State
The printer state describes the status of the printer:
Printing
Waiting
Offline
Suspended
Deverror
Procerror
Selection Algorithm
For each printer, the spooler maintains a queue, which is a list of the jobs to be printed
on the printer. The job at the head of the queue is the next job to be printed.

The printer is in the process of printing a job but has been suspended by
