Printer/Interface Operation
(For Computer commands, see "Printing" in this manual.)
ADAPTER
JACK
The silver-gray but¬
ton provided at
the bottom of this
unit is intended to
reduce the influ¬
ence of static elec¬
tricity generated
on the printer.
Therefore, the but¬
ton has nothing
to do with the
general operation
of this unit.
(5) LOW BATTERY INDICATOR
1. Power Switch
The POWER switch turns the Printer/Interface ON and OFF. The paper
will automatically advance on power-up to indicate that the Printer is
ready. (This initial paper advance will not occur if the battery is too
weak.) The POWER switch must be ON for printer and cassette operation.
Note: If you turn the power OFF (or ON), wait at least one second before
turning it back ON (or OFF).
2. Print Switch
The PRINT switch activates the Printer. When the PRINT and POWER
switches are ON and the Computer is in Print Mode (see below), PRINT
and LIST commands will go to the Printer. If the PRINT or POWER
switch is OFF, the PRINT and LIST commands will go to the Display.
Print Mode. To put the Computer in the Print Mode, press the
Computer's ON key twice after you turn the Printer's POWER and PRINT
switches ON. The Computer's output (PRINT and LIST) will then go to
the Printer instead of to the Computer's Display.
