Printer sharing doesn't work with Sonoma on new imac

I have a Brother printer attached to my new iMac with Sonoma. I downloaded to it the appropriate printer driver and local printing works. However, we have another computer which used to be able to print to this same printer while I was using the old mac with Mojave. Now the other computer can no longer print. I enabled sharing as sown on the attachment. All I spend my time with is trying to figure out how to make things work with Sonoma.... Is there anything else I should try to make things work as prior to the new computer with Sonoma? Thanks
