While I'm working on the receipt printer, I found this nice code to send the raw text to printer. You will have more freedom and control over the print out.
function doPrint(rawText) {
var printWindow = window.open();
printWindow.document.open('text/plain')
printWindow.document.write(rawText);
printWindow.document.close();
printWindow.focus();
printWindow.print();
printWindow.close();
}

Notes
In the receipt printer driver, goto Advanced tab and change the driver to "generic/text only". Then, the following codes will print the raw text.
