MacBook Pro doesn’t “see” my wireless printer to be online

I’ve been printing from my MacBook Pro for a few years on to my wireless Epson WF-100 printer just fine. A little while ago, my Mac recognizes my printer, but it doesn’t detect it to be online, even thou the printer IS online, connected to the same network as the Mac, Wi-Fi is working properly. Since I was able to print, I didn’t change anything in the settings, but it just never sees my printer to be online. What can the problem be?
