AirPrint over Ethernet????

AirPrint as a network protocol (actually it uses a several IP Network Protocols) doesn’t care whether the network is WiFi or wired Ethernet. The protocols themselves are all IP-based; as such, an AirPrint print-server installed on a wired network segment will work quite happily.

However, most consumer-grade AirPrint printers, featuring multiple interfaces (e.g. have a single WiFi network interface plus a USB interface - or feature multiple network interfaces such as WiFi plus a wired Ethernet port), generally only implement AirPrint on the WiFi network interface. In such cases, the printer must connect to the network via WiFi for AirPrint to function.

So, to accurately answer your question, yes and no.

a) Where AirPrint is explicitly supported by your your printer or connected print server over its wired Ethernet port - then yes, you are theoretically able to print from your iPad to AirPrint enabled devices connected to your wired Ethernet network segment.

b) As most consumer-grade printers only support AirPrint over their WiFi network - then no, it may not be possible to directly print from your iPad.

In summary, AirPrint is IP-based, but its implementation on a specific network interface is at the behest of the printer manufacturer.

I hope this clarification is helpful in resolving the question.

Hello,

AirPrint only functions over Wi-Fi.
