Invalid TFTP printer message

[wasisnt]

We have some Epson receipt printers and occasionally they start printing out the following message over and over.

Invalid TFTP Operation
Exiting Firmware Update...

If you turn them off and on sometimes it will stop for awhile. We don't have any TFTP servers on the network or anything that uses TFTP. I read that it can be caused by a router or other Cisco device. My coworker was changing some settings on a Cisco switch but has been done for awhile.

I need to make this stop so they can use the printers!

Thanks

Figured it out. An interface on one of our routers was just enable and it was sending out the broadcast. We disabled the interface for now until we figure out how to stop it.
