Greetings,
Maybe this will help:
The D420's connection interface is USB.
It does not have any networking capability and thus, "Wake On LAN" is not a feature supported by this type of connection.
In your case, the printer connected to your MAC is "shared" which means other devices on your network can find the D420 and print to it when your MAC is on, but not when its sleeping or off.
There is only one true solution. Buy a network capable printer. One that has wireless or Ethernet connection. This will take your MAC out of the equation and allow devices to print regardless of whats present, turned on, off, etc.
