I am developing a centralized printing system using LPRng 3.8.2 on RH Linux 7.2. A couple of questions have arisen:
* When a job is received by an lpr queue, is the JobId (the parameter in the control file prefixed by 'A') assigned to it globally unique (relative to all jobs currently residing on _all_ print queues), locally unique (relative to all jobs on its current print queue), or globally unique "for all time" (even after the print job is removed from the system no other print job on any other queue will have that same JobID, at least until the lpd service is restarted). (This last would be ideal for my purposes, but I fear it is not the case.) Why is this important? I need to have some way to keep track of all print jobs that go through our lpr system over time, and it seems as if there is no unique identifier that lpr uses. That is, it is possible that there could be two print jobs (not in the system at the same time) whose control files are identical (except, perhaps, for the date field). * I have noticed a curious phenomenom. At times, as a print job winds it way through various print queues (for validation and authentication purposes) the "J" field in its control file changes! When it does this, it seems as if it is replaced by some other job's JobName. This is causing no end of confusion. Has anyone else ever seen this behavior? (Unfortunately, I cannot figure out any pattern to when this happens, so I cannot duplicate it on demand.) I appreciate any and all comments and suggestions. Thanks, A.
