On the official website of the product, there is nothing mentioned about the possible incompatibilities with some printers. In this case, if you have your Argox printer properly installed, it should appear in the printing menu. To install the printer on your computer, you need to visit its manufacturer's website, search for your device and download the appropriate drivers. After you had installed the printer, and the printer test is completed, open the Mr Price Group WEB Print Labels, and under File > Print, you should be able to find your printer.
