You can control it.
Well, I made a printer.
First start the scene, to turn on or off the lasers (that read and write) press down. The thing that takes the laser can move right and left and the other moves with a and s. Use the texture floppies on the sheet textures and vice versa. Insert the floppies in the floppy reader. The textures sheet I made it in pieces for make it more real
(like a real printer).

P.S.:Never use a texture floppy in the text sheet.
