STATUS/INFORMATION

Get Printer Status ESC (0x1b) 'h' (0x68)

This command requests a status byte from the printer.

If one is returned, it indicates that the printer is opera-

tional and has finished processing the previous label.

It should be called before loading or printing a label in

order to make sure that the host software is synchro-

nized with the printer.  If bit 3 of the status byte is high,

it indicates that the battery is low.  If bit 4 is high, it

indicates that the printer has been powered on and

reset (see the Reset Status function).  This command

requests a status byte from the printer with the follow-

ing format:

Bit

Description

4

Printer reset (0=reset cleared, 1=printer reset)

3

Battery status (0=voltage OK, 1=low battery)

2

Latch status (0=latch closed, 1=latch open)

1

Paper status (0=paper present, 1= out of paper)

0

Printer status (0=printer ready, 1=printer busy)

Acknowledge Printer Reset ESC (0x1b) 'N' (0x4e)

This command clears the reset bit that is set on

power-up and reported by the 'get printer status'

function.  The reset information returned by ESC 'h'

may be used by the host to perform its printer power-

up initializations, such as form-feeding.  Once the host

completes its initialization of the printer, it may call this

function to tell the printer to clear its reset bit.
