When I set up network printers, wired or wireless, I always assign a fixed IP address to them to prevent loss of connectivity. I make sure that the assigned IP address (or address range for multiple printers) is not part of the range that is being used for the DHCP Server service that assigns IP addresses to other network devices.

If the printer was showing "Receiving Data", and the IP address was changed, it may have been receiving data intended for a different device that now had the IP address formerly used by the printer.
