Reception of Status Event
The status event notification function is used to check the printer status without printing. (in firmware Ver.1.2
and later) Refer to the following:
//Set the end point address
var address = 'http://192.168.192.168/cgi-bin/epos/service.cgi?devid=local_printer

&timeout=10000';
//Create an ePOS-Print Builder object
var builder = new epson.ePOSBuilder(address);
//Set an event callback function (cover open)
epos.oncoveropen = function () {
alert('coveropen');
};
//Set an event callback function (paper near end)
epos.onpapernearend = function () {
alert('papernearend');
};
//Enable status event operation
epos.open();
