The printer/spooler selection allows configuration of form queues by program and/or port number and user id. There is also an option to view, kill, move, print and fax spooler
entries.

As you use Profi'C, very often you will make an inquiry to the system or you will want a report. If you choose to display the system output on your screen, your spooler is not involved. However, if you want the system output to print on a printer or be recorded on a tape drive, the job involves a SPOOLER.

 Let's look briefly at what happens when you ask Profi'C to print, for example, a report. First, you send the report request from your terminal to the host computer which gathers and formats the output. As this is happening, your terminal is tied up. Without a spooler, the report, as it is printing out, will tie up your terminal. Until the physical printing is actually completed, your terminal would be unusable for any other task. How do we free your terminal to perform other tasks during a printing job? We use a spooler. Think of the spooler as a temporary holding tank for printing jobs. Like a buffer, the spooler takes over the moment the data from a print job is gathered and formatted. The spooler executes the actual printing job freeing up your terminal to perform another task.
