###What is the difference between qz-print and qz-tray? qz-tray uses websockets to communicate to the browser without the use of NPAPI. In order for qz-print to work, NPAPI must be enabled in the web browser to work. This is a concern because Google (Chrome) has disabled NPAPI in a recent update. NPAPI can be re-enabled, but this ability will be blocked later this year (sometime around September).
