Hi there, We're seeing a problem whereby a printer (in this example, an HP8150DN, but other HP printers have also shown the same symptoms) shows significant delays between the completion of one job printing and the next one in the queue starting.
lpc -kill <queue> or restarting lpd doesn't fix the problem, neither does power-cycling the printer. We're running LPRng 3.8.21 with our own print filters. Communication is direct to port 9100 (e.g. printcap contains lp=printer.inf.ed.ac.uk%9100) Here's some (edited for clarity) information from status.pr: # here's a job that's just finishing... printing finished at 2003-11-27-14:33:14.630 ## accounting at end at 2003-11-27-14:33:19.411 ## finished '[EMAIL PROTECTED]', status 'JSUCC' at 2003-11-27-14:33:19.411 ## # at this stage, the job has printed out, but there's a lengthy # delay.... waiting for subserver to exit at 2003-11-27-14:37:19.605 ## # there's a wait of approximately 4 minutes before this appears, and # immediately the next job starts going... subserver pid 23697 exit status 'JSUCC' at 2003-11-27-14:37:19.605 ## printer%9100: job '[EMAIL PROTECTED]' printed at 2003-11-27-14:37:19.605 ## job '[EMAIL PROTECTED]' removed at 2003-11-27-14:37:19.606 ## subserver pid 23825 starting at 2003-11-27-14:37:29.897 ## So, what seems to happen is that lpd is waiting for a process to return and say that the job has printed, and this process is taking a long time to come back - long after the job has been printed. It seems like this problem is much worse when there are lots of jobs in the queue - in the case today, when there were 50+ jobs in the queue, the wait was between 4 and 5 - now that the queue is down to 18 jobs, the wait is a little over a minute. Could this be the cause? I haven't been able to verify this bit because I've only ever been notified about it when there are a lot of jobs in the queue. Can anyone suggest any solutions or even things to try? I'm a bit stumped as to what to do next.
