FernFlower: NVM asked cloudy

== Keymapper API ==

The keymapper API was intended to assist with deciphering os.pullEvent("key") calls. os.pullEvent("char") basically replicates the conditions that it was intended to solve, and that's why os.pullEvent("char") was the only one I listed in the deprecated statement. Can you explain to me your reasoning for including key events in the notice? [[User:Riking|Riking]]

== Random Reverts? ==
Hello its mandrake again. and I would like to ask why you keep reverting like a madman?! I wanted that page deleted for a reason. The code on that page is old and outdated and did not work back in 1.3 or so when i tried it.

Printer

2012-10-24T14:10:46Z

FernFlower:

The printer was added in the [[ComputerCraft]] 1.42 update. The printer is placed next to a computer, and allows for printing text onto paper with any color of ink.

== Recipe ==
{{Crafting grid
|A1=stone |B1=stone |C1=stone
|A2=stone |B2=redstone_dust |C2=stone
|A3=stone |B3=Ink_Sac |C3=stone
|Output=printer
}}
== Usage ==
To use a printer, place it adjacently but not diagonally next to a computer (left, right, top, bottom, front, or back side). Place any color ink in the single left slot, and paper in any of the top slots.

If you are using blocks to pull/insert items from the printer the diffrent slots are avaible from these sides:
Paper tray is accessible from the top, output paper tray is accessible from the front or bottom, and the ink slot is accessible from the back or sides.
