Printer error (EX_TIMEOUT) Epson TM-T88V-I with epson.ePOSBuilder

Question

Epson model TM-T88V-i.
Connected to LAN.
Ping response OK.
Printing status sheet OK.
I have access to printer configuration page.

http://192.168.x.x/PrinterConfigurationPage/
In configuration page - section devices raise error in test print button for the printer "local_printer", error: "EX_TIMEOUT A time-out ocurred".

reference (ePOS-Print API/XML):
https://download.epson-biz.com/modules/community/index.php?content_subject=ePOS-Print%20API/XML

simple test web site:

print.html

<script type="text/javascript" src="js/epos-print-3.0.0.js"></script>

code

function printTest() {
    // open print dialog
    $('#print').dialog('open');

    //
    // build print data
    //

    // create print data builder object
    var builder = new epson.ePOSBuilder();

    builder.addText('Test Print\n');
    builder.addFeedLine(1);

    // append paper cutting
    builder.addCut();

    //
    // send print data
    //

    // create print object
    var url = 'http://192.168.x.x/cgi-bin/epos/service.cgi?devid=local_printer&timeout=6000';
    var epos = new epson.ePOSPrint(url);

    // register callback function
    epos.onreceive = function (res) {
        // close print dialog
        $('#print').dialog('close');
        // print failure
        if (!res.success) {
            // show error message
            $('#receive').dialog('open');
        }
    }

    // register callback function
    epos.onerror = function (err) {
        // close print dialog
        $('#print').dialog('close');
        // show error message
        $('#error').dialog('open');
    }

    // send
    epos.send(builder.toString());

}

Two possibilities:

Your printer has a device id that is different from local_printer - check the configuration page.

Or the ePOSPrint() function does not allow sending the url directly. What I have on my first test page (I'm working on building an app for the same printer right now) looks different than on yours:

var epos = new epson.ePOSPrint();
epos.address = 'http://192.168.0.1/cgi-bin/epos/services.cgi?devid=local_printer&timeout=6000';

Note the empty () and how the url is delivered after initialization.

After checking, it looks like some other test code I have does submit the url as parameter to the function like you have it, so my only guess is that the device id local_printer is incorrect.
