| Item ID | 4094 |
| Damage Value | Un-used. |
| Peripheral? | Yes- Printer (API) |
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.
Recipes
Using the printer will produce Printed Page. These pages can be used in two different shapeless recipes: Printed Pages and Printed Books. Using any of these when on your hotbar will allow you to view their contents (much like with signed books in vanilla).
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 different slots are available 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.
Printer API
The printer API allows programs to interact in various ways with the printer. In order for these functions to become available, you must first wrap the printer as a peripheral using peripheral.wrap().
