Using the EPSON Spool Manager

The EPSON Spool Manager is similar to Windows Print Manager.
If it receives two or more print jobs at one time, it holds them in
the order that they were received (with printers on a network this
may be cancelled a print queue). When a print job reaches the top
of the line, the EPSON Spool Manager sends the job to the printer.
Note:
EPSON Spool Manager is not available for Windows NT 4.0.
