ps402d-Print service from 402d

PS402D is a driver for monochrome (grayscale) printing from your smartphone or tablet to a network printer. Install the app. Print in the usual way. And the application will automatically find AirPrint compatible printers on your local network.

The main thing is not to forget to turn on Wi-Fi.

Which printers are supported ?
At the moment, more than 9 thousand printer models have been released that support network printing using AirPrint + IPP protocols.

My printer is not detected, what should I do?
1) Check that you are connected to the same Wi-Fi network as the printer. To search for printers, the mDNS protocol is used, which is not routed. That is, UDP packets go only in one subnet.
2) The printer must understand the tasks in the uimage/urf (unicast) format
