In this post I will show you how to print a ticket or receipt by using JavaScript (client side) and a thermal printer. At the end we will have a great ticket that looks like this:

Ticket sample

Receipt printed in thermal printer using JavaScript only

Obviously you can change the font family, size, logo and so on. And remember: we will be using only pure CSS, HTML & JavaScript, no frameworks; though you can use any framework to render the content before printing.

You can see the demo here, and the full code on my GitHub.

Designing the ticket

First we have to write the HTML to print the ticket, in this case I will use a table to render the contents in a better way. Also, I’m using a image taken from pixabay. The code looks like this:

Remember: this is a static example, you can always use a framework (client side or server side) to render the content in a dynamic way.

We have some CSS Classes, for example “centered”. We have a button to print the ticket as well and we are loading a CSS file to give style.

Styiling receipt

Now we have to give some style to our receipt. Here’s the CSS code:

I’m giving a fixed width to each thing, this way we take a small space because the thermal paper is narrow. So far we have this:

Receipt in JavaScript

Now we can print the ticket, or make the button to print it.

Hidding the button

In CSS we have the hidden-print class, that class is used to hide the button when we print the receipt.

Printing ticket in thermal printer

The JavaScript code is small. It is like this:

We are only calling window.print to tell the browser to print the document. When we press it, depending on the browser, a window appears, and there we can select the printer and some features.

Note: if you want to hide the dialog, you can use my plugin.

I am using Chrome, the thermal printer I have is a Xprinter 58, please note that I am not using any margins, so we can take the full space:

And when I click “Print” Chrome sends the receipt to the printer and we have this:

Ticket sampleConclusion

In this way we can print anything by using a Thermal printer, CSS, HTML and JavaScript. The only issue is that we have to confirm the action, but I have developed the solution by using a plugin.

Hey! Thank you very much for taking the time to write this. Very informative! However, I do have a silly question. You mentioned that you are using an Xprinter 58 – could you be more specific which one exactly your using? I want to avoid buying one and then not being able to print as you described in your post. would perhaps the following do the trick? (sorry for the long link)

    Yes, the printer in the link is correct; I have an identical one.
    Regards 🙂

    parzibyte · January 16, 2020 at 1:34 pm

I have a question regard the page size. Maybe it’s me not understanding how thermal printers work. But I’m building an app where a section of HTML is to be printed. For some reason when our client tested it the whole roll of paper was being used.

Basically my question is whether there’s a way to set the page height to be printed? Or is this something that is handled automatically by the printer?

    parzibyte · January 13, 2020 at 11:45 am

    Maybe you should define a page height in your HTML and set properly your paper size. I was having the same errors so i developed a plugin: https://parzibyte.github.io/plugin-ticket-js/en/

    Regards 🙂

    Daniel Grima · January 14, 2020 at 1:41 am

    Yes the page height might be the issue. I’ll have to continue testing 🙂 thanks for your reply!

Hi. Did you use any external library to print using the thermal printer? I am building a php based point of sale project and so far all my research was pointing to using some external library eg – escpos-php.

Also what brand was the printer you used?

Thanks and would really appreciate your help!
