I assume it's turned on and connected to the router.
Sometimes with DHCP, the IP address on the printer will change. I end up going into the router table to see what IP addresses are assigned where. Invariably I'll find my network printer has changed. Find the printer and write it down.

In Windows, Go into Printers> choose the Brother and right click to check Properties. Look for Ports and change the IP address as needed. It will come back online.

I had this same problem when printing photos. Go into printing preferences, then the Advanced tab up top.....make sure "Color Mode" has NONE selected. That lets the program you are using do the color management.
