Launching the Spooler
The Spooler is launched automatically when you print a
document (if background printing is on). To view the
Spooler window, select SuperScript 870 Spooler from the
Finder menu in the upper right corner of your screen.
You can also open this window when there are no
documents being printed (or when background printing is
off), by double-clicking on the SuperScript 870 Spooler icon
in the Extensions Folder inside the System Folder.
The Spooler shows information about the job currently
being printed and lists jobs waiting in the print queue.
