Hooking Up the Printer and Computer
This printer comes with a bidirectional parallel data interface. You must
supply the required interface cable for your application.
CAUTIONS:Keep the power switch in the OFF position when
attaching the interface cable.
The power supply barrel connector must be inserted
into the power supply receptacle on the back of the
printer before connecting or disconnecting the com
-
munications cables.
This printer complies with FCC “Rules and Regula
-
tions,” Part 15, for Class B Equipment, using fully
shielded six-foot data cables. Use of longer cables or
unshielded cables may increase radiated emissions
above the Class B limits.
Parallel Interface Requirements
The required cable (IEEE 1284-compliant is recommended) must have a
standard 36-pin parallel connector on one end, which is plugged into the
parallel port located on the back of the printer. The other end of the parallel
interface cable connects to the printer connector at the host computer.
For pinout information, refer to page 57.
Interface Cable Requirements
Data cables must be of fully shielded construction and fitted with metal or
metalized connector shells. Shielded cables and connectors are required to
prevent radiation and reception of electrical noise.
To minimize electrical noise pickup in the cable:
Keep data cables as short as possible (6’ [1.83 m] recommended).
Do not tightly bundle the data cables with power cords.
Do not tie the data cables to power wire conduits.
