Printing 101

Here is a review of some basic terminology and print management concepts, to help individuals new to managing some areas of 400 stuff.

Spool

A spooled file (sometimes called a spooled output file) is a file that holds output waiting to be printed. At any given time, multiple spooled files can be waiting to print.

• • You see only your own spooled files unless you have job control (*JOBCTL) or spool control (*SPLCTL) special security authority.
  • On the S/36 there was only one spool file with all output for all users.

Printer Writer

• A printer writer is a system program that writes spooled files to a printer.
  • On S/36 a spool writer prints output that is saved in the spool file.

Output Queue

• An output queue contains a list of spooled files that are waiting to be printed. There can be multiple output queues.
  • On S/36, a spool file is equivalent to an AS/400 output queue
  • On S/38 only one spool file was available and it contained all outpuyt waiting to be printed.

Lose track of reports =

Sometimes a report is created, and now we can't find it. Here are some possibilities to consider:

• It was printed, laid on your desk, then some other report was laid on your desk on top of the one you looking for.
• It was printed, along with a bunch of other reports for some other person. On that person desk is now continuous printed lots of their reports, with yours sandwiched in between.
• It never printed. It is waiting on someone to respond to some printer error message.
  • Perhaps someone needs to push the start button on the printer, after someone else stopped the printer to make it easy to tear off forms, then forgot to restart it.
  • Perhaps someone needs to check alignment. When forms get changed, the 400 needs to be told that humans know what they are doing, the right forms in there, and they aligned satisfactorily.
  • Perhaps someone saw error message, did not read it carefully, assumed it was a different message, made the right reply to the wrong message.
