RatOS off the network, still printing

Here's a fun one. I started a print through ratos.local, and at some point, the connection failed, and I can't reconnect. The "ratos" is off the network, not even pulling an IP address... but the printer is still going. Any way to get it back online, without killing the print? Pretty sure I can't reboot the pi, since it streams the file over to the control board, right?
