QMS 860, User Manual, Page: 63 / 398

Handler icon to display a window containing LaserWriter
(among other things).
c. Copy the LaserWriter file by dragging the icon onto the System
Folder icon on your hard disk or start-up disk. System 6 users
should have the LaserWriter file located in the System Folder.
System 7 users should have the LaserWriter file located in the
Extensions Folder within the System Folder.
NOTE: All Macintosh users on a network must use the same
version of the LaserWriter and Laser Prep files to run
correctly. For example, if the network has a mixture of
LaserWriter 6.0 and 7.0, the printer will experience frequent
reinitialization problems. To check the version number, select
the LaserWriter icon and then hold down the Command key
and press I. The driver version number appears in the Info
window on the second to last line. LaserWriter 7.xx does not
require a Laser Prep file to work correctly with your printer.
The Laser Prep information is located within the LaserWriter
driver itself.
Printer Description Files
In addition to LaserWriter and Laser Prep, many Macintosh
applications, including Aldus PageMaker, Aldus FreeHand, Adobe
Separator, and QuarkXPress, use special printer description files.
PS Executive Series Utilities includes these special files, called
APD (Aldus Printer Description), PPD (PostScript Printer
Description), PDX (Printer Description eXtension), and PDF
(Printer Description File). See “Using the Macintosh Utilities” in
the PS Executive Series Utilities documentation for details.
Adobe Separator uses the PPD file. You have to tell Separator
where the PPD is located on your Macintosh. Check your Adobe
documentation for details.
