"No Printer" but I've entered access code, etc

Sometimes these printers can be a royal PITA. Bambu Studio says I have no printer (of course I’ve had it for a couple years). Instructions to Bind With Access Code instruct me to enter IP addr, access code, and serial number. I do so. Still no connection.

It’s on the same network it’s always been on. No PW’s have been changed. My network is working and connected to the internet. The computer I am on is connected to the same LAN.

All I want to do is use my printer. I would appreciate some advice. Thanks.
