3.4. Other codes

(1) DC 1 (Device Control 1)

The DC 1 code places the Printer in the Selected state. It enables the Printer to receive data.

With the Printer in the Selected state, if the DC 1 code is input during data transfer, all data stored before the DC 1 code is ignored.

(2) DC 3 (Device Control 3)

The DC 3 code places the Printer in the Deselected state. In other words, it disables the Printer to receive data. Once the Printer is put in the Deselected state by the DC 3 code, the Printer will not revert to the Selected state unless the DC 1 code is input again.

NOTE: When the DC 1 and DC 3 codes are used, the DIP switch pin 1-8 on the control

circuit board should be in the “OFF” position.

(3)ESC 8 (Escape 8) (to ignore the Paper End detector)

The ESC 8 code makes it possible to transmit data even if there is no paper in

the Printer. Since this code causes the PE signal to be ignored, data may be printed to the last page of the form without waste of paper. With the DIP

switch pin

l-6 on the

control circuit board set in

the ON position, the Printer

is placed

in the ESC

8 condition upon application

of power.

(4)ESC 9 (Escape 9)

This code cancels the ESC 8 condition, and reinstates the PE signal. Therefore, the Printer cannot receive data when there is no paper. With the DIP switch pin l-6 set in the OFF position, the Printer is placed in the ESC 9 condition upon application of power.

(5) BEL (Bell)

When the BE L code is input, the buzzer sounds for about 1 second.

Arbitrary use of this code is recommended to arouse the attention of the operator.

(6) BS (Back Space)

The BS code cancels the data immediately preceding this code in the Text Mode. In other words, one byte data stored prior to the BS code is cleared from the print buffer, as though that data has not been transferred from the host computer. Note that this code is valid only in the Text Mode.
