list number of prints in queue

[srhoads]

Anybody know how to list the number of prints in a print queue?

I am writing a program to automatically print thousands of engineering drawings and want it to loop and possibly display an error message if there are too many drawings already in the queue.

You need to [exec] a system command.
This command is system dependant.

Under Windows you can use NET PRINT.

Under UNIX/Linux you can use lpq.
