To make a parallel cable to use for PLIP, you will need two 25-pin connectors (called DB-25) and a cable with at least eleven conductors. The cable must not be any longer than 15 meters (50 feet). The cable may or may not have a shield, but if you are building a long cable, it is probably a good idea to have one.
If you look at the connector, you should be able to read tiny numbers at the base of each pin—from 1 for the pin at the top left (if you hold the broader side up) to 25 for the pin at the bottom right. For the null printer cable, you have to connect the following pins of both connectors with each other, as shown in Figure B-1.
All remaining pins remain unconnected. If the cable is shielded, the shield should be connected to the DB-25's metallic shell on just one end.
