Robert:
If the Imagewriter has an Appletalk card installed and the Laserwriters
have Localtalk ports, then you will be able to share them with your network
of Ethernet Macs. To share them however, requires a slight shift in your
connectivity plans.
Option #1
Connect all your Localtalk printers (and any Localtalk Macs) together
either via star controller. This Localtalk network would then need to be
connected to the Ethernet network via a router. The router enables the two
networks to communicate with each other. You can connect up to 48 LocalTalk
devices to Ethernet with one product if you purchase a StarRouter from
Farallon (http://www.farallon.com).
(Localtalk devices)--[StarRouter]--(Ethernet devices)
Option #2
Farallon also makes another product called LocalPath which is a software
solution to connecting up to 8 LocalTalk devices to Ethernet.
I don't have any experience with the software option, but I can vouch for
the hardware option. Farallon products are excellent and they have
Educational Institution Discounts.
