The first patent filed by Apple outlines the driver-less printing process as discovering a universal printer via a discovery protocol such as Bonjour, the use of a network printing protocol such as IPP as well as PostScript Printer Description (PPD) file capability. The three components can be implemented via one or more APIs that enable any application to access a printer without the need for an additional driver, Apple said. The network connection could be established via different types of network connections, such as Bluetooth, 3G/4G, Wi-Fi 802.11, 802.15 or “any” peer-to-peer wireless or wired “networking technology.”
