IEEE 1284 Parallel Cable Information This cable is IEEE compliant with A-to-C connectors. To take advantage of its enhanced capabilities such as bidirectional communication between the computer and printer, faster transmission of data, and auto configuration of printer drivers, the customer must have the following: G Support in software applications for these features. G A parallel cable with the correct pin configuration (see below). Parallel Cable Pin Configuration For best results, use the C2946A (3 meter) or C2947A (10 meter) cable or equivalent. CAUTION Ensure that all power and interface cables on the printer and host computer are properly grounded in compliance with local codes.
