If it is, how? And will I need to set a canvas size before hand?
If you are connected it via network, especially over WIFI, be sure it is still connected to network. Sometimes you get printer disconnected HP scanner not working from WiFi for one reason or another and might need to reestablish connection,If it is connected by physical cable such as USB or Ethernet, then be sure cable is securely plugged. Very often when someone or pets in house hold tripped on cable, things get loose or sometimes even damage cable.
