<P>If you try to spool too large a file, it will be truncated.
lpr will object to printing binary FILES. If a user other than root prints
a file and spooling is disabled, lpr will print a message saying so and will not put jobs in the queue. If a connection to
lpd(1) on the local machine cannot be made, lpr will say that the daemon cannot be started. DIAGNOSTICS may be printed in
the daemon's log file regarding missing spool FILES by
lpd(1).

<P>lprm—Remove jobs from the line printer spooling queue
</P>
<P><B>SYNOPSIS</B></P>
<!-- CODE SNIP //-->
<PRE>lprm [-P printer] [- job # ...] [user ...]
</PRE>
<!-- END CODE SNIP //-->
<P><B>DESCRIPTION</B></P>
<P>lprm will remove a job, or jobs, from a printer's spool queue. Since the spooling directory is protected from users, using
lprm is normally the only method by which a user may remove a job. The owner of a job is determined by the user's login
name and hostname on the machine where the lpr(1) command was invoked.
</P>
<P>OPTIONS and arguments:
<TABLE>
<TR><TD>
-P printer
</TD><TD>
Specify the queue associated with a specific printer; otherwise, the default printer is used.
</TD></TR><TR><TD>
-
</TD><TD>
If a single - is given, lprm will remove all jobs that a user owns. If the superuser employs this flag, the
spool queue will be emptied entirely.
</TD></TR><TR><TD>
user
</TD><TD>
Causes lprm to attempt to remove any jobs queued belonging to that user (or users). This form of
invoking lprm is useful only to the superuser.
</TD></TR><TR><TD>
job #
</TD><TD>
A user may dequeue an individual job by specifying its job number. This number may be obtained
from the lpq(1) program. For example
</TD></TR></TABLE>
<!-- CODE SNIP //-->
<PRE> lpq _ -l
1st:ken [job#013ucbarpa]
(standard input) 100 bytes
lprm 13
</PRE>
<!-- END CODE SNIP //-->
<P>If neither arguments nor OPTIONS are given, lprm
will delete the currently active job if it is owned by the user who
invoked lprm.
</P>
<P>lprm announces the names of any FILES it removes and is silent if there are no jobs in the queue that match the request list.
</P>
<P>lprm will kill off an active daemon, if necessary, before removing any spooling FILES. If a daemon is killed, a new one
is automatically restarted upon completion of file removals.

<P>Because there are race conditions possible in the update of the

<P>lptest—Generate line printer ripple pattern
</P>
<P><B>SYNOPSIS</B></P>
<!-- CODE SNIP //-->
<PRE WIDTH="1">lptest [length] [count]
</PRE>
<!-- END CODE SNIP //-->
<P><B>DESCRIPTION</B></P>
<P>lptest writes the traditional "ripple test" pattern on standard output. In 96 lines, this pattern will print all 96
printable ASCII characters in each position. Although originally created to test printers, it is quite useful for testing terminals,
driving terminal ports for debugging purposes, or any other task where a quick supply of random data is needed.
</P>
<P>The length argument specifies the output line length if the default length of 79 is inappropriate.
</P>
<P>The count argument specifies the number of output lines to be generated if the default count of
200 is inappropriate. Note that if count is to be specified,
length must also be specified.
</P>
<P><B>HISTORY</B></P>
<P>lptest appeared in BSD 4.3.
