It may be if it's given a different IP address, as your devices may be looking for the original address that was issued to the printer when you first setup.
If you're using a HH3, I think (I've only used a Business Hub 3, so there may be differences) you can set the router to assign the same address to the printer every time (so 'pseudo' static) via DHCP.
Have a look in Advanced Settings -> Network -> Devices
You should be able to click on the printer and then select an option 'Always use this IP address' which will reserve and use the current assigned address for the printer only.
