Apple LaserWriter 12/640 PS - Manual (Page 353)

First use the printed manual to set up your printer. The printed manual
contains setup and installation information.
Next go to the onscreen manual to learn how to use your printer. The file
is in Adobe Portable Document Format (PDF). To read or print the
documentation, you use the Acrobat Reader software on the CD-ROM
disc. The PDF file is located at MAC_OS:Monochrome LaserWriter:
LW12/640UM.pdf and WIN_OS\MONO_LSR\LW12/640U.pdf on the
CD-ROM disc.
The onscreen manual includes additional setup information (for example,
how to name your printer) and continues (beginning with Chapter 5) with
usage information, troubleshooting, and technical information about
your printer.
IMPORTANT If you already have Acrobat Reader installed on your computer,
you do not need to install it from the CD-ROM disc. If you do install Acrobat
Reader from the CD-ROM disc, an Adobe Acrobat folder may appear as the
active folder on your screen, blocking access to the onscreen manual. Close
the Acrobat folder (or drag it out of the way) so you can open the onscreen
manual.
