OOPs, that IP is from your Modem and I'll ask it be edited out because it's your Outside IP, so don't be shocked or dismayed! 🙂
Also, I feel a bit helpless in my new enviorment, after spending 15+ on the PC side.
Don't worry, somebody here can help I'm certain of that, not too sure of myself though!
BTW, I think if the student doesn't learn, it's the Teacher's fault, not the Student's! 😉
I've never done this without a Router, but I doubt your Printer's IP starts with the same 3 IP numbers, nor do I think it would help if it did.
If we can find the IP of the Printer we may find a workaround.
We need to find your Cann setup Utility to find out or setup te Printer.
Might try the Apple icon up top left>About this Mac>More info>Hardware>Printers, then see if it is listed, and if it shows an IP.
