GS (1D)H

Validation printing instruction

This code causes the printer to perform validation printing of a maximum of 32 subsequent characters (at 15 CPI, from the thirteenth to the forty-forth column).

After the GS code is received, a maximum of 32 characters should be input, followed by the LF code which indicates the end of the validation printing data.

(At this time, control codes except FS, ENQ, CAN and SUB codes, or any character received beyond the limit of 32 characters are ignored.)

When the printer enters the validation mode, the ribbon is shifted up and the ON-LINE lamp blinks. (This lamp goes on and off at a 0.5-second interval until the end of the va- lidation mode.) After the material to be validated is inserted, and the LF button is pressed, the validate line is printed, followed by a single line feed. When the check is removed and the ON-LINE button is pressed, the printer returns to regular mode and is set to ON-LINE status.

1)The print settings by commands (such as emphasized mode and underline mode) are invalid only during val- idation printing.

2)When the CAN code is received in the validation mode, the printer returns to regular mode, and the mechanism is initialized.

3)If the FS or SUB codes is received in the validation mode, these codes are executed just after the printer returns to regular mode.

4)In the validation mode, the LF button and the ON-LINE button do not work except the above behavior.

5)If the printer has a Red black ribbon installed, the va- lidate line will be printed in red.
