Zebra Technologies 2844 Printer - Manual (Page 19)

Hooking Up the Printer and Computer
Your printer will have one of two combinations of interfaces:
�
Universal Serial Bus (USB), parallel and serial
�
USB, ethernet, and serial
Each specific interface option—USB, parallel, ethernet, serial—is discussed
individually.
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.
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.
