NETWORK PRINTING
Hardware connections
Print servers can be internal or external devices.
Which one you choose depends on your printer.
Internal print servers -- These are special-
purpose cards or modules that plug into the
built-in input/output slot in the back of some
printers. The slot provides the data and power
connections for the print server, and the
network cable plugs into the network connector
on the face of the print server.
Internal print servers come in a variety of
configurations to match the style of your printer
slot and the type of network connection you
need.
External print servers -- External print
servers are for printers that don't have a built-in
slot. The print server is a small module that sits
next to the printer (or mounts on the printer
using a clip) and connects to the printer's USB
or parallel port using a standard printer cable. A
network cable plugs into the network connector
on the print server, and a power cord connects
to a wall outlet to provide the print server's
power. (We haven't shown the power cord in the
illustration, just to keep the drawing simpler.)
External print servers come in several different
configurations to match the printer's data port
(USB or parallel) and the type of network
connection you need.
