Request alternate status (A793 emulation only)

ASCII ESC u n

Hexadecimal 1B 75 n

Decimal 27 117 n

Value and Range of n:

Value of n Function Description

00 Drawer 1 High = Open

Low = Closed or Not Present

01 Drawer 2 High = Open

Low = Closed or Not Present

02 Paper Low High = Paper Out

(Not Implemented. Low = Paper Present

Interpreted as

Paper Out.)

03 Paper Out (Default) High = Paper Out

Low = Paper Present

>03 Ignored, No Change Printer Does Not Stay BUSY1

1PAPER EXHAUST LINE is valid to indicate previously requested status.

This command allows the printer to inform the host when the data in the buffer has been processed. The PAPER

EXHAUST line shows the status for the cash drawer or receipt paper as shown in the table.

Status information is limited to what can be sent by the dedicated lines: BUSY, ACK, PAPER EXHAUST, and FAULT.

Exceptions

Parallel communications only.

Transmit paper sensor status

ASCII ESC v

Hexadecimal 1B 76

Decimal 27 118

Values:

Status Byte (RS-232C)

Bit Function 0 Signies 1 Signies

0 Receipt paper Present Low (only if paper low sensor is enabled)

1 Receipt cover Closed Open

2 Receipt paper Present Out

3 Knife position Home position Not home position

4 Not used Fixed to zero Fixed to zero

5 Temperature In valid range Too hot or too cold

6 Voltage In valid range Too high or too low

7 Not used Fixed to zero Fixed to zero

Sends status data to the host computer. The printer sends one byte to the host computer when it is not busy or in a fault

condition. In DTS/DSR protocol, the printer waits for DSR = SPACE.

reporting.

In LEGACY emulation, this command is ignored.
