iPF 8400s cancels all print jobs sent from network

[MarkSauls]

My iPF8400s wide format printer has started canceling all print jobs sent via the network.

I can print when plugged in via USB

not sure what to do?

I've deleted printer, downloaded and reinstalled driver program.

when installing the setup doesn't "see" the printer but it accepts it when i manual key the IP

I can login to printer via browser on network and see the print jobs all say cancelled.

also restarted printer and PC several times.

Windows 10, 64bit
