.SH NAME
lpsched \- start the LP print service
.SH SYNOPSIS
.LP
.nf
\fBlpsched\fR [\fB-f\fR \fInum_filters\fR] [\fB-n\fR \fInum_notifiers\fR] [\fB-p\fR \fIfd_limit\fR]

.SH DESCRIPTION
.sp
.LP
The  \fBlpsched\fR command  starts or restarts the  \fBLP\fR print service.
.sp
.LP
The  \fBlpshut\fR command stops the  \fBLP\fR print service.  Printers that are
restarted using \fBlpsched\fR reprint (in their entirety) print requests that
were stopped by  \fBlpshut\fR. See  \fBlpshut\fR(1M).
.sp
.LP
It is recommended that you start  and stop the LP print service using
\fBsvcadm\fR(1M).  See \fBNOTES\fR.
.SH OPTIONS
.sp

The following options are supported:
.sp
.ne 2
.mk
.na
\fB\fB-f\fR\fI num_filters\fR\fR
.ad
.RS 20n
.rt  
Specifies the number of concurrent slow filters that may be run on a print
server. A default value of \fB1\fR is used if none is specified. Depending on
server configuration, a value of  \fB1\fR may cause printers to remain idle
while there are jobs queued to them.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-n\fR\fI num_notifiers\fR\fR
.ad
.RS 20n
.rt  
Specifies the number of concurrent notification processes that can run on a
print server. A default value of  \fB1\fR is used when none is specified.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-p\fR\fI fd_limit\fR\fR
.ad
.RS 20n
.rt  
Specifies the file descriptor resource limit for the  \fBlpsched\fR process. A
default value of  \fB4096\fR is used if none is specified. On extremely large
and active print servers, it may be necessary to increase this value.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-r\fR\fI reserved_fds\fR\fR
.ad
.RS 20n
.rt  
Specifies the number of file descriptors that the scheduler reserves for

when none is specified. It should not be necessary to modify this value unless
instructed to do so when troubleshooting problems under high load.
