2.5.2 Installing an External Parallel Printer or Floppy Drive

The Notebook is equipped with an external, bidirectional, ECC/EPP compatible, 25-pin

parallel printer port. The connector pinouts and connector location are shown in Figure

2-5. When used with a special cable, an external floppy disk drive may also be attached

to the notebook via the parallel port. When a floppy disk drive is connected to the parallel

port, the floppy disk drive in the Modular Bay is disabled, if present.
