lpsched(1M) lpsched(1M)

NAME

lpsched, lpshut, lpmove, lpfence - start the LP request scheduler, stop the LP request scheduler, move

requests between LP destinations, and deﬁne the minimum priority for printing

SYNOPSIS

/usr/sbin/lpsched

[ -v ][-a ]

/usr/sbin/lpshut

/usr/sbin/lpmove

requests dest

/usr/sbin/lpmove

dest1 dest2

/usr/sbin/lpfence

printer fence

DESCRIPTION

lpsched Schedules requests taken by lp(1) for printing on printers. lpsched(1M) is typically invoked

/sbin/rc. This creates a process which runs in the background until

lpshut is exe-

cuted. The activity of the process is recorded in

/var/adm/lp/log.

lpsched recognizes the following options:

-v Write a verbose record of the

lpsched process on /var/adm/lp/log

-a Write lpana(1M) logging data on

/var/adm/lp/lpana.log

lpshut Shuts down the printer scheduler. All printers that are printing at the time lpshut is

invoked stop printing. Requests that were printing at the time the scheduler was shut down

are reprinted in their entirety after lpsched is started again. All LP commands perform

their functions even when lpsched is not running.

lpmove Moves requests that were queued by lp(1) between LP destinations. This command can be

used only when lpsched is not running.

The ﬁrst form of the command moves the named requests to the

LP destination, dest.

requests are request ids as returned by lp(1). The second form moves all requests for desti-

nation dest1 to destination dest2. As a side effect, dest1 rejects requests.

Note that

lpmove never checks the acceptance status (see accept(1M)) for the new destina-

tion when moving requests.

lpfence Deﬁnes the minimum required priority for the spooled ﬁle to be printed. fence must be in

between 0 (lowest fence) and 7 (highest fence). Each printer has its own fence, which is ini-

tialized to 0 when it is conﬁgured by the lpadmin(1M) command.

lpfence is used only

when lpsched is not running.

EXTERNAL INFLUENCES

Environment Variables

LC_TIME determines the format and contents of date and time strings.

LANG determines the language in which messages are displayed.

LC_TIME is not speciﬁed in the environment or is set to the empty string, the value of LANG is used as a

default for each unspeciﬁed or empty variable. If LANG is not speciﬁed or is set to the empty string, a

default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an

invalid setting, the commands behave as if all internationalization variables are set to "C". See

environ(5).

WARNINGS

lpsched, lpshut, lpmove, and lpfence perform their operation on the local system only.
