LaserWriter driver 6.0.2 is included with System Software 6.0.7, in the
Apple Color folder on the Printing Tools disk. The only difference between
LaserWriter driver 6.0.1 and LaserWriter driver 6.0.2 is that LaserWriter
driver 6.0.2 has an added resource for printing envelopes.
In Page Setup, you now have the options of either printing envelopes from
the edge or from the center. This was done for the Personal LaserWriter.
Manual feed on a LaserWriter II has two paper guides which move in and out
together, allowing you to print from the center. Manual feed on the
Personal LaserWriter has only one paper guide, which moves from the edge
out. You would, therefore, want to put the envelope all the way over to the
edge. LaserWriter driver 6.0.2 gives you the option to do this.
