Tim,

Huh! Hadn't thought of that.

The printer is on and 'Ready':
# nmap -O -sV -sU -sS 192.168.55.192
Starting Nmap 7.12 ( https://nmap.org ) at 2019-10-24 11:23 PDT
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 0.96 seconds

Cable or switch suddenly gone bad?

No. It doesn't have that capability.
