Using the PDG for iOS/macOS devices without Bonjour
iOS and macOS devices use the Bonjour protocol for printer discovery. However, in many cases, the Bonjour protocol is not robust enough to overcome certain deployment scenarios. The limitations of Bonjour, and as a result native print for iOS, can make it either difficult or impossible to maintain a functional printing infrastructure.
You can use the Print Delivery Gateway to provide the same benefits of the native iOS print workflow without the need for Bonjour. To accomplish this, PDG uses other tools to inform iOS devices how and where to find printers on a network.
