G.2.2 Power off process by the host
The following is an example of the printer power off process when the printer is turned off using the
DLE DC4 (fn = 2) command.
1) The host transmits the following continuous procedure before the system is turned off:
➀
Executes the last print command such as LF, ESC d, etc.
➁
Executes GS ( D p
L
p
H
m a b (p
L
=3, p
H
=0, m =20, a =2, b =1)
➂
Executes GS r n (n =1)
2) The host waits for the paper sensor status sent from the printer in response to the GS r n
command.
3) The host transmits DLE DC4 fn a b (fn =2, a =1, b =8).
4) The host waits for the power off status.
•
The values of the maintenance counter are stored and the power-off sequence is
performed within 10 seconds after the host transmits DLE DC4 fn a b; then the power off
status is transmitted.
•
If the power off status is not checked, the host waits for 10 seconds or more after
transmitting DLE DC4 fn a b.
•
For the serial interface model, the printer status is transmitted regardless of the condition
of the host.
•
For the parallel interface model, after the host transmits DLE DC4 fn a b, the printer is
required to be ready for receiving data from the host.
NOTE: The printer executes the software sequence, but the power is not cut.
5) Please turn the host power off.
NOTE: Do not execute a reset to the printer until the printer power is turned off after
transmitting DLE DC4 (fn = 2).
