LPSCHED(ADM) UNIX System V
Name
lpsched, lpshut, lpmove - start/stop the print service and
move requests
Syntax
/usr/lib/lpsched
/usr/lib/lpsched -q integer
/usr/lib/lpsched -a integer
/usr/lib/lpsched -p integer
/usr/lib/lpsched -s integer
/usr/lib/lpshut
/usr/lib/lpmove requests dest
/usr/lib/lpmove dest1 dest2
Description
lpsched starts the LP print service; this can be done only
by root or lp.
lpshut shuts down the print service. All printers that are
printing at the time lpshut is invoked will stop printing.
When lpsched is started again, requests that were printing
at the time a printer was shut down will be reprinted from
the beginning.
lpmove moves requests that were queued by lp between LP
destinations. The first form of the command moves the named
requests to the LP destination dest. Requests are request-
ids as returned by lp. The second form moves all requests
for destination dest1 to destination dest2; lp will then
reject any new requests for dest1.
Note that when moving requests, lpmove never checks the
acceptance status (see accept(ADM)) of the new destination.
Also, the request ID of the moved request is not changed so
that users can still find their requests. The lpmove
command will not move requests that have options (content
type, form required, and so on) that cannot be handled by
the new destination.
-q integer
Specify the number of request structures you want to
allocate.
-a integer
Specify the number of alert structures you want to
allocate. By default, forty empty alert structures are
allocated in addition to one for each printer or form
on the system. Structures will always be allocated for
existing printers and forms. You can choose, however,
to have more or fewer than the forty extra, by using
the -a option. For example, if you want only as many
alert structures as you have printers and forms on your
system, enter the following command: lpsched -a 0.
-p integer
Specify the number of print status structures you want
to allocate. By default, twenty-five empty printer
status structures are allocated in addition to one for
each printer on the system. Structures will always be
allocated for existing printers. You can choose,
however, to have more or fewer than the forty extra, by
using the -p option.
-s integer
Specify the number of slow filters per printer that can
be run simultaneously.
Notes
By default, the directory /usr/spool/lp is used to hold all
the files used by the LP print service. This can be changed
by setting the SPOOLDIR environment variable to another
directory before running lpsched. If you do this, you
should populate the directory with the same files and
directories found under /usr/spool/lp; the LP print service
will not automatically create them. Also, the SPOOLDIR
variable must then be set before any of the other LP print
service commands are run.
Files
/usr/spool/lp/*

Authorization
The behavior of this utility is affected by assignment of
the lp authorization, which is usually reserved for system
administrators.
