It does not remove any jobs from the queue 53(use the \fIlprm\fP command instead). 54.I Start 55enables printing and requests \fIlpd\fP to start printing jobs. 56.LP 57\fBenable\fP and \fBdisable\fP 58.IP 59\fIEnable\fP and \fIdisable\fP allow spooling in the local queue to be 60turned on/off. 61This will allow/prevent 62.I lpr 63from putting new jobs in the spool queue. It is frequently convenient 64to turn spooling off while testing new line printer filters since the 65.I root 66user can still use 67.I lpr 68to put jobs in the queue but no one else can. 69The other main use is to prevent users from putting jobs in the queue 70when the printer is expected to be unavailable for a long time. 71.LP 72\fBrestart\fP 73.IP 74.I Restart 75allows ordinary users to restart printer daemons when 76.I lpq 77reports that there is no daemon present. 78.LP 79\fBstop\fP 80.IP 81.I Stop 82halts a spooling daemon after the current job completes; 83this also disables printing. This is a clean way to shutdown a 84printer to do maintenance, etc. Note that users can still enter jobs in a 85spool queue while a printer is 86.IR stopped . 87.LP 88\fBtopq\fP 89.IP 90.I Topq 91places jobs at the top of a printer queue. This can be used 92to reorder high priority jobs since 93.I lpr 94only provides first-come-first-serve ordering of jobs.
