treh1966 commented 5 years ago

Actually it is in the source with comment: // a pulse of 25 ms worked quite fine with my cash drawer so i set it as default PULSE_PIN2_DEFAULT: new Buffer('1B70001919','hex').toString('utf8'), PULSE_PIN5_DEFAULT: new Buffer('1B70011919','hex').toString('utf8'), PULSE: function(pin,ontime,offtime){ if (pin==2){ var pinHexString = '00'; }else{ var pinHexString = '01'; } var command = new Buffer('1B70'+pinHexString+("00"+ontime.toString(16)).slice(-2)+("00"+offtime.toString(16)).slice(-2),'hex').toString('utf8'); return command; }

In my app i simply call it like this: Printer.append(Printer.ESCPOS_CMD.PULSE_PIN2_DEFAULT);
