Making the
Connection
3-3 Connecting to a PC
(IEEE 1284 is indicated on the cable). This cable must be 6.5
feet/2 meters or less in length.
n If your computer supports only Centronics (IEEE 488) unidirec-
tional communication, you may use either an Centronics parallel
cable (unmarked on cable) or an IEEE 1284 bidirectional parallel
cable (IEEE 1284 is indicated on the cable). However, we recom-
mend an IEEE 1284 cable. The IEEE 1284 cable must be 6.5
feet/2 meters or less in length while the Centronics cable may be
longer.
Serial cable—If the printer is more than about 6.5 feet/2 meters from
the computer, we recommend using a serial cable for better commu-
nication. For best results, the serial cable should be less than 25 feet/
7.6 meters long.
Making the Connection
O Caution: If you’re connecting the printer to a single PC, turn off both systems
first.
