Choosing an Interface
This section describes the interfaces.
IEEE-488 and Apple interfaces
The IEEE-488 system allows you to connect computers, printers, and
other peripherals so that they can share data freely Epson offers two
types of IEEE488 interfaces. The #8161 offers the basic ability to
operate in the IEEE-488 address and listen-only modes. The *8165 has
the basic features and an 8K data buffer and a line monitor function,
which provides a diagnostic printout of IEEE488 commands.
The Apple II, II + and He computers do not have a printer interface as
a standard feature. Epson produces a parallel interface board for the
Apple, which has software to control the functions of the printer. With
the *8131 interface installed in the Apple, no additional interface is
needed in the printer An An Apple IIC requires only a suitable cable for use
with the LQ.
Buffered interfaces
If you often print very large amounts of text, a buffered interface can
free the computer for other tasks. Serial and parallel buffered interfaces
are
available to increase the printer’s data buffering capacity to either
32K or 128K (about 20 and 80 pages). See Table F-1.

Serial interfaces
The built-in serial interface on LQ printers is suitable for almost all
applications. If, however, you need an interface that allows different
serial settings or that conforms to the Current Loop standard rather than
Rs232C, you can install an optional interface.
