Chapter 11: Memory and Option Cards
Tri-Port Interface
Option Card
The Tri-Port interface option card lets you connect to:
• A LocalTalk network
• Serial interface (RS-232C or Serial RS-422A)
• An infrared adapter
For information about the LocalTalk network, see “Local-
Talk Menu” on page 96.
For more information about serial interface, see “Serial
Menu” on page 87.
An infrared adapter receives an infrared beam that allows
you to print remotely to an IrDA-compatible computer.
For more information, see “Infrared Menu” on page 93.
Installing the Tri-Port Interface Option Card
To install, complete the following two sections in order:
• “Accessing the Printer System Board” on page 201
• “Installing an Option Card” on page 216
Hard Disk Option
Like the flash memory option, the hard disk option is use-
ful for storing information such as downloaded fonts,
macros, and symbol sets.
Note: Data stored on the hard
disk option is kept in memory
when the printer is turned off.
You can also use the hard disk option to store incoming
print jobs in a buffer until they print. Since hard disk
memory provides permanent storage, job buffering to the

loses power. It may also free your application faster for
other work. Job buffering is only available for jobs trans-
mitted across the standard parallel and USB interface.
