3 PRINTER FUNCTION

3.1 Buffer Full Printing

The DPU-414 has a line buffer to receive data in one-line units.

If data with more columns than one line is received, printing will start,

even if there is no print command.

This is called "Buffer full printing".

3.2 Interval Home Return

To protect the printer, the head returns to the home position (the leftmost

position) automatically when;

 data is not sent from the computer

 the ONLINE button is pressed to set the printer OFFLINE

 the printer runs out of the thermal paper

3.3 Errors

Both the ONLINE and OFFLINE LEDs and data input and paper feed are

disabled when one of the following four errors occurs:

A The head does not return to the home position even when the power is

turned on;

B The head does not return to the home position at interval home return;

C Printing is attempted at extremely low or high ambient temperatures;

D The battery runs out;
