The functionality of this block has been merged with the Pattern Grid in Refined Storage for Minecraft 1.12.2.
A Processing Pattern Encoder is used to create patterns meant for machine automation.
It takes up to 9 inputs and 9 outputs, so the storage network knows what to take and what to expect.
This block can't be connected to a storage network.
The Processing Pattern Encoder integrates with JEI (Just Enough Items) so the player can use recipe transferring.
When using this, Refined Storage will use the inputs and outputs that the JEI recipe has.
