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. (B

Solution 1:

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:

<inputtype=buttononClick="print()"value="Print"><appletid="qz"code="qz.PrintApplet.class"archive="./qz-print.jar"width="100"height="100"><paramname="printer"value="zebra"></applet><script>functionprint() {
       qz.append("PRINTED USING JZEBRA\n");
       qz.print();
      }
</script>

Solution 2:

This is very old question, but it is still difficult to find a good solution. I used to use QZ Tray solution (as Tres Finocchiaro has described), but now I think I've found a better one that provides full control over the process:

1. Register custom protocol (like "https", "http", "mailto") named, for instance, "print". It is done using registry editor in Windows.
2. Write a custom protocol handing application which will be automatically executed by Windows when somebody is going to open a link like "print://any/parameters/go/here".
3. Implement printing in your application. I'm using C# and built-in PrintDocument class, so it is extremely simple.

Now I can just create a link with href like "print://invoice/1234" and then parse this URI in your application and print whatever you need. It works even from a command line.

Here you can get more information.

Solution 3:

a solution: Have a look at jQPrint

EDIT:

Have a look at jQuery or other javascript plugins that do this, try jQPrint if it's still supported or try searching if the link is broken. I realise this is an old answer and they type of answer that is no longer permitted. Hopefully this helps.
