Receipt Printer - print from webpage
I have a receipt Printer and it connected to Serial COM1 on to my comuter.
I am trying to print a receipt from the webpage and when it print... it just a blank without any text. (Blank receipt!). It work fine on IE8 but not working on Firefox 3.6
I have an Epson TM-T88II Printer and using "Generic / Text" driver on Windows 7.
What is the solution to this?
HTML code of receipt:
<html>
<head>
<title></title>
</head>
<body>
<div>
<div>Company Name</div>
<div>Customer Name</div>
<div>Order No</div>
<div>1 x Item</div>
<div>1 x Item</div>
<div>1 x Item</div>
<div>12.00</div>
</div>
</body>
</html>
Answer
If you are willing to load a java applet, jzebra can print directly to the Epsom TM series thermal printers to COM1 port using the Generic Text driver as you've described.

The problem you are encountering is not uncommon. Generic/Text bypasses the PostScript (2D) capabilities of the Epson print driver.
If using Generic/Text, Epson uses the ESC/P programming language. You will find many tutorials on the internet for printing in this format, and jzebra has more information about this style of "RAW" printing here:

Edit:
To get this working, simply setup your receipt printer as the default printer and rename it as "zebra":
Then simply download the qz-print library, put the jar file in the project directory and hey presto:
<input type=button onClick="print()" value="Print">
<applet id="qz" code="qz.PrintApplet.class" archive="./qz-print.jar" width="100" height="100">
<param name="printer" value="zebra">
</applet>
<script>
function print() {
qz.append("PRINTED USING JZEBRA\n");
qz.print();
}
</script>
