What are the opening codes for an Epson-driven cash drawer?
ASCII = ESC p 0 25 250Decimal = 27 112 0 25 250
HEX = 1B 70 00 19 FA
There are 5 separate pieces of data that must be sent down. The data is broken down (in ASCII) as follows:
ESC p = the command to send a pulse to the drawer kick port
0 = open drawer #1. Change this to 1 if you want to open drawer #2
25 = the height of the pulse
250 = the duration of the pulse
