Here's a little bit of code that you can insert to replace the printESCP function in sample.html:

function printESCP() {
        var config = getUpdatedConfig();

        var printData = [
            '\x1B' + '\x40', // init
        '\x1B' + '\x61' + '\x31', // center align
        'Canastota, NY  13032' + '\x0A',
        '\x0A', // line break
        'www.qzindustries.com' + '\x0A', // text and line break
        '\x0A', // line break
        '\x0A', // line break
        'November 21, 2015 3:09 PM' + '\x0A',
        '\x0A', // line break
        '\x0A', // line break         
        '\x0A',
        'Transaction # 123456 Register: 3' + '\x0A',         
        '\x0A',         
        '\x0A',         
        '\x0A',
        '\x1B' + '\x61' + '\x30', // left align
        'Baklava (Qty 4)                     9.00' + '\x1B' + '\x74' + '\x13' + '\xAA', //print special character symbol after numeric value
        '\x0A',
        'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + '\x0A',         
        '\x1B' + '\x45' + '\x0D', // bold on
        'Here\'s some bold text!',
        '\x1B' + '\x45' + '\x0A', // bold off
        '\x0A' + '\x0A',
        '\x1B' + '\x61' + '\x32', // right align
        '\x1B' + '\x21' + '\x30', // em mode on
        'DRINK ME',
        '\x1B' + '\x21' + '\x0A' + '\x1B' + '\x45' + '\x0A', // em mode off
        '\x0A' + '\x0A',
        '\x1B' + '\x61' + '\x30', // left align
        '------------------------------------------' + '\x0A',
        '\x1B' + '\x4D' + '\x31', // small text
        'EAT ME' + '\x0A',
        '\x1B' + '\x4D' + '\x30', // normal text
        '------------------------------------------' + '\x0A',
        'normal text',
        '\x1B' + '\x61' + '\x30', // left align
        '\x0A' + '\x0A' + '\x0A' + '\x0A' + '\x0A' + '\x0A' + '\x0A',
        '\x1B' + '\x69', // cut paper
       
        ];

        qz.print(config, printData).catch(displayError);
    }

Barcodes are a little more involved, but you can find most of the commands on-line in pdf format like this:

http://www.delfi.com/SupportDL/Epson/Manuals/TM-T88IV/Programming%20manual%20APG_1005_receipt.pdf (5.1MB)

ESCP is also known as ESC/POS, ESCP2, and other variants, but the vast majority of the commands will be the same.

Programming guides will reveal which commands have been deprecated over the years, and font sizes are usually printer-specific.

Kind regards,

Thanks Lite, I will give it a go.

Good evening, I have a question about what the function contains:
var config = getUpdatedConfig();

[Lite Finocchiaro]

getUpdatedConfig()

Generally refers to the config (printer, options) being used in sample.html

It is not common outside of our demo in my experience.

Lite is correct, it's for our sample.html file.  It crawls the sample to update the config object.
