A: INSTALLING THE PRINTER INTERFACE CARD
If you are not going to use the printer through the Printer Interface Card,
skip sections 'A'and 'B' and go straight to section 'C'.
However, we recommend that you install the Printer Interface Card
Driver at this point whether or not you intend to use the printer through
the Printer Interface Card.

Caution
DO NOT remove the Printer Interface Card and the PC Card Cable when
LEDs are on or blinking. Before you remove them, press the
button and wait until all the LEDs are off.
Note
Before installing the Printer Interface Card Driver, check that your
computer is connected to a live power source or your computer has
enough battery power left.
If you remove the printer cable or turn the printer off while you are
inserting the Printer Interface Card into the PC Card slot, and the
printer does not work correctly after that, remove the Printer Interface
Card from the slot and insert the card again and re-start the Printer
Interface Card Driver installation.
Before you install the PC Card Driver, be sure to set the Power Save
mode of your computer off. For details, see your computer's manual.
