You can put any item into a printer using a funnel, crashing the game.

Describe the Bug

If you use a conveyor belt and a funnel (any type), you can put anything inside a printer, and it looks like there isn't any checks to verify if there is actually a book inside. This will results in a crash, however, if you try to access the world again it will crash again because the item is still in the printer, this essentially locks you out of your world.

This is a major bug which could lock everyone out of a multiplayer server and crash it.

Reproduction Steps

⚠️Be warned. This completely disables your world until an update that fixes this gets released, don't try it in a world you actually use.⚠️

1. Place a printer
2. Setup a moving conveyor belt with a funnel in order to put items on the printer
3. Try to place anything besides a book in the printer using the conveyor belt.

Expected Result

The printer will not accept the item, or if it does, it'll just not work instead of crashing.
