Error handling
Refer to the following program for the error handling method by a callback function.
//Create an ePOS-Print object
var epos = new epson.ePOSPrint(address);
// Set a response receipt callback function
epos.onreceive = function (res) {
// Obtain the print result and error code
var msg = 'Print' + (res.success ? 'Success' : 'Failure') + '\
nCode:' + res.code 
+ '\
nStatus:\n';
// Obtain the printer status
var asb = res.status;
if (asb & epos.ASB_NO_RESPONSE) {
msg += ' No printer response\n';
}
if (asb & epos.ASB_PRINT_SUCCESS) {
