lp print queue limit?

[Dave Parker]

Can anyone tell me if there is a limit on the number of print jobs in an lp print queue?

It is 10,000. You have noticed the 4-digit sequence at the end of the job (queue name). It will go up to 9999 and then wrap around to 0000. When it reaches an existing job number it will stop.
Actually if in the emantime there are any gaps in the sequence it will find them and reuse them. Otherwise the lp command does not return the prompt.

In case you are going to use these in some scripting, the jobs 0000-0999 show without the leading zeroes in the sequemce. i.e. quename-0, quename-1, quename-12, quename-999.

Thanks,

We are going to be performing an upgrade to our software that stores reports. I need to queue up all the reports printed over 4-5 days (approx 10,000 reports/day). I guess I will have to setup multiple queues and move the reports to separate queues when they are almost full.
