The Personal LaserWriter LS Prep file is in fact a "serial" driver needed
for systems running System Software 6.0.7. System 7 contains this new
serial driver, making the prep unnecessary.
There are two versions of the Personal LaserWriter LS "printer" driver: the
one shipping originally with the printer, version 1.0, and the latest
version that ships with System 7, version 7.0. The System 7 driver is
preferred as it is faster and contains solutions to earlier problems; this
version is compatible with systems running System Software 6.0.7 when used
with the (version 1.0) Personal LaserWriter LS Prep file.
