Connecting hardware to JTL-POS

You can use a variety of hardware with JTL-POS. If you connect a printer, you can print receipts. With a separate display, you can show purchase information to the customer. By using TSS components, you make your cash register legally secure.

How to


JTL-POS supports many types of printers which can be connected via all common interfaces, e.g. Bluetooth, USB, or via a network. You will almost certainly work with a receipt printer, which you must initially connect to JTL-POS.

There are print templates for the receipt and the day-end closing report which you can modify as you see fit.


JTL-POS CustomerDisplay is a valuable addition to JTL-POS as it perfectly rounds off your customers’ shopping experience and their overall impression of your point of sale. On your own screen, first display the current checkout process and then the QR code with which customers can load the digital receipt onto their smartphone. Or use the customer display for marketing purposes and draw attention to current offers, discounts or your online shop through advertising banners, slideshows and videos. To optimally present your brand, the app offers you numerous possibilities to easily customise the design of the displayed content.
