Mac can't find printer
I recently upgraded my home network and the wireless modem is now in the basement. I installed an Arris VAP2500 wireless access point in the study and plugged the printer's ethernet cable into it. Now, my Mac no longer recognizes the printer. They are both on the same wireless network (both IP addresses start with 172.16.1).
I am running Mac OS Catalina 10.15.6 on a Mac Mini with 8 Gb of memory. The printer is a Xerox Phaser 6180N
