Optional Interfaces

with the optional interface card.
Initialization
The printer can be initialized (returned to a fixed set of
conditions) in these ways:
Hardware
initialization
∗
The printer is turned on.
∗
The printer receives an
INIT
signal from the
parallel interface: pin 31 goes LOW.
Software
initialization
∗
Software sends the ESC @ (initialize the printer)
command. The last panel settings are kept.
Control panel
initialization
∗
Hold down the Alt button and press the Pause
button (buffer clear). The last panel settings are
kept.
All three initialization methods reset the font according to
the default settings selected using the control panel.
However, ESC @ does not initialize the printer mechanism,
clear the input data buffer, or clear the user-defined character
set. The control panel initialization does not initialize the
printer mechanism or clear the user-defined character set.

In addition, hardware and control panel initialization erases
any text in the data buffer.
Control Panel
The printer’s front control panel contains lights for
displaying the printer status and buttons for controlling
certain settings.
Since most printer settings can be controlled from software,
you do not often need to use the control panel. This section
describes how to read the lights and the buttons on the
control panel.
Lights
Operate
On when the printer is on. Flashes when the
printer is turned on or off.
Data
On when data is being received by the printer
or when data remains in printer memory.
Paper Out
On when the printer runs out of paper. Rapid
flashing indicates a paper jam.
No Ink
Cartridge
On when one or both ink cartridges are not
installed. The printer will not work unless
both cartridges are installed.
Font
Indicates the font selected through the control
panel. Because you normally choose fonts
from your software, ignore this light.
Economy
On when economy printing mode is selected.
In economy mode the printer uses less ink by
printing fewer dots per character. Use this
mode for rough drafts of text only.
