It does not remove any jobs from the queue +(use the \fIlprm\fP command instead). +.I Start +enables printing and requests \fIlpd\fP to start printing jobs. +.LP +\fBenable\fP and \fBdisable\fP +.IP +\fIEnable\fP and \fIdisable\fP allow spooling in the local queue to be +turned on/off. +This will allow/prevent +.I lpr +from putting new jobs in the spool queue. It is frequently convenient +to turn spooling off while testing new line printer filters since the +.I root +user can still use +.I lpr +to put jobs in the queue but no one else can. +The other main use is to prevent users from putting jobs in the queue +when the printer is expected to be unavailable for a long time. +.LP +\fBrestart\fP +.IP +.I Restart +allows ordinary users to restart printer daemons when +.I lpq +reports that there is no daemon present. +.LP +\fBstop\fP +.IP +.I Stop +halts a spooling daemon after the current job completes; +this also disables printing. This is a clean way to shutdown a +printer to do maintenance, etc. Note that users can still enter jobs in a +spool queue while a printer is +.IR stopped . +.LP +\fBtopq\fP +.IP +.I Topq +places jobs at the top of a printer queue. This can be used +to reorder high priority jobs since +.I lpr +only provides first-come-first-serve ordering of jobs. |
