For detailed information about ESC/POS commands, see the ESC/POS Command Reference that can be accessed
from the following URL.

S.2 Controlling the Cash Drawer (Model for specified customer only)
A pulse output is sent to drawer kick connector pin 2 or pin 5, and you can open the drawer.
You can also check the open/close status of the drawer by checking the signal level of the drawer kick connector pin
3.
These controls are executed by a driver or by commands.
Note: Whether or not pin 2 or pin 5 operates the drawer kick connector depends on the connected cash drawer.

Prepare the output command for the specified pulse and the status transmission command. For details, see the
ESC/POS Command Reference.
S.2.2 For Windows Printer Drivers (APD)
You can set the drawer to open when printing is started. For details, see the manual for drivers. For details on
control, see the manual for Status API of the driver.
