AppleShare PC has no need for the 7.0 LaserWriter driver or its prep
information (also called Laser Prep, md, or Macintosh Dictionary).
When AppleShare PC prints to a LaserWriter, it uses one of two methods,
depending on how it's connected. If it's set up for Epson LQ-2500
emulation, an emulation dictionary downloads with each job. This doesn't
interfere with md (if it is present) and is purged at the end of the job.
If AppleShare PC is set up for PostScript printing, no dictionaries
download at all. Only data made by the MS-DOS application are used. These
data pass directly to the LaserWriter without changes. These data can
cause problems depending on the application's print driver requirements. We
haven't yet done any testing yet but don't expect any compatibility
problems.
