Hi,

We are having trouble using BrowserPrint to send a printing job to our Zebra ZD421 via the network. When connecting with USB it works, but we need it to work over the network as well. Can you help us fix this issue?

The printer is online and can be accessed via the network.

We have manually added the IP address and port in BrowserPrint and the host is accepted. When changing the default device, the printer is not automatically discovered which is why we manually added it.

From the logs:

556076 NanoHttpd Request Processor (#3) ERROR c.z.d.w.c.d.k - Unauthorized device detected

I hope someone is able to help :)

Best,
