If you need printer-sharing between VAX terminals (MicroVAX, for instance) and
one Macintosh Plus using a LaserWriter IINT or IINTX, the simplest solution
would be to use the one Macintosh Plus system as a terminal.
This can be accomplished through the use of one of the many terminal emulators
available. This also prevents you from having to install a network for just
one machine's needs.
Another possibility is to upload PostScript output files from the Macintosh
to the MicroVAX and have the VAX print them. These files can be generated
by holding down the Command and 'k' keys when printing using the LaserWriter
drivers. A disk file is then generated instead of actually printing to a
LaserWriter.
A third possibility is installing an Ethernet between the MicroVAX and a
FastPath and connecting the FastPath and the Macintosh Plus together through
an AppleTalk network. The MicroVAX would need to be running LaserWriter
spooling software that would allow it to accept files over the network from
the Macintosh Plus.
The drawback with such a setup is that users of WordPerfect on the MicroVAX
might not be able to use the printer if the software on the MicroVAX is unable
to accept print jobs from multiple (different) sources.
