My iMac Sequoia 15.6.1 cannot find my Brother Printer MFC-J895DW

I've had the printer for a number of years and it works great. After upgrade, it suddenly had error message, Printer off-line. But it was on, I'd previously switched to Air Print. I tried removing printer to re-add it, but now it can't find it at all. Is this fixable or is this version of Sequoia incompatible?

Thank you!
