Recently most of the major browsers have stopped working with Java as a security precaution. This has caused some issues for our POS users as it is not possible to print directly to a printer in a web browser and we use a Java App to automatically print to the printer.
Next week we will announce the release candidate of 18.2 which will include a major upgrade to the POS system. In 18.2, the POS will include a new desktop application with an embedded browser (like the login screen in version 18.x). In 18.2, we will be using the desktop application to communicate directly with the printer, eliminating the java applet altogether. The POS in 18.2 will also include the EMV chip and sign feature.
Look for the announcement coming soon!
