ESC S
Description: Puts the printer in sleep mode
Format: <1Bh>
<53h>
Comments: This command puts the printer in sleep mode giving the major benefit of zero power
consumption. Before going into sleep mode, the printer will relay back the same code
(ESC S) to the serial or parallel port (depending of which interface selected), and then it
shuts down. The serial and parallel communication voltage levels must be turned to zero to
reduce any leakage current inside the printer (except INIT on the parallel port than must
remain at level 1).
There are 3 ways of waking the printer up:
·
Through the parallel port by activating the \INIT signal (resets the printer)
·
Through the serial port by sending the character “00 hex” (wake-up character)
·
Press the paper feed button
Note:
1.
During sleep mode, all signals except \INIT must be turned to logic 0. If they are not,
unexpected results may occur on the sleep mode function.
2. Wait 500 ms before sending the next character for the printer to execute the power-up
sequence.
3. When waking-up through the serial port, the wake-up character will be ignored.
ESC A n
Description: Set the autosleep time
Format: <1Bh>
<41h> <n>
Comments: n = 0 to 255: (Default n = 0: feature disabled) This command puts the printer in sleep mode
when no print activity has occurred after a certain. Timeout is n * 5 seconds.
