Regardless of the architecture
of your network, and the mix of workstations from other platforms,
printing requires that somewhere across the network an accessible
printer is cabled to a server or workstation. That connection is
based on a particular type of communication channel, the pathway
which dictates the signals used and the methods employed to control
the transfer of print data to the printer. This appendix discusses
the primary communication channels in use, including serial and
parallel connections, Hewlett-Packard Remote Printer connections,
and AppleTalk connections.
