This is the response from our MAC guru here when helping with this same issue a year ago:
You can easily assign the printer a static IP address on all routers (except starlink). I'd go a step further and remove it from printers and scanners applet in Mac OS. Use the minus key (-). Restart your system and then install it as an IP printer using the address you assigned in your router.
In the add printer dialogue use the globe icon which is just to the right of the printer icon. Specify the IP address as the destination. You will note that the printer name dialog (below) will populate with the same IP address. This field is editable, give your printer a friendly name something meaningful to you. Select the printer driver in the drop-down below that you already have installed.
This will accomplish several things. First, it will ensure that the printer always gets the same IP address on your network regardless of how often it's used, whether it goes to sleep or is turned off for an extended period of time. Print jobs sent from the computer where it is installed will always use this IP address as the destination. Further, any device that connects to the same network will always be able to find the printer at its statically assigned "destination IP". This ensures a persistent and reliable connection. Best of all this only has to be done once, set and forget.
