[[File:PrintedPage.png|thumb|Viewing a printed page]]

The printed page is an item which is created with the [[printer]]. The contents of the page can be viewed by right clicking with it on the hotbar. Two or more can be crafted together with a string to create [[Printed Pages|printed pages]], or crafted together with a string and a piece of leather to create a [[printed book]].

Printed pages are 25 characters wide and 21 characters tall.

Printed Page can't be read by computers. If you want to save a program, use a [[Floppy Disk]] instead.

Peripheral.find

{{Function
|name=peripheral.find
|args={{type|string}} type [, {{type|function}} fnFilter( name, object )]
|returns={{Type|table}} handle1, {{Type|table}} handle2, ... handles to peripherals of the given type
|api=peripheral
|addon=ComputerCraft
|desc=Introduced by ComputerCraft 1.6, returns a list of handles for connected peripherals that match the supplied type (essentially performing as a filtered version of [[peripheral.wrap|peripheral.wrap()]]).<br><br>

A custom function may additionally be passed as a parameter - if it's supplied, each matching peripheral's name and handle will be passed to it during the search, and they'll only be included in the final results if it returns "true".
|examples=
{{Example
|desc=Finds a monitor and writes 'Hello' on it.
|code= local monitor = '''peripheral.find("monitor")'''

if monitor then
monitor.[[term.write|write]]("Hello")
end
|output=If there is a monitor connected 'Hello' will be written on it.
}}
{{Example
|desc=Finds 2 '''advanced''' monitors and writes 'Hello' on the first and 'World' on the second.
|code= local mon1, mon2 = '''peripheral.find("monitor", function(name, object) return object.isColour() end)'''

if mon1 then
mon1.[[term.setTextColor|setTextColour]]([[colors|colours]].blue)
mon1.[[term.write|write]]("Hello")
end
if mon2 then
mon2.[[term.setTextColor|setTextColour]]([[colors|colours]].red)
mon2.[[term.write|write]]("World")
end
|output=If it finds 1 advanced monitor, 'Hello' will be written on it. If it finds 2 advanced monitors, 'Hello' will be written on the first and 'World' on the second.
}}
}}

{{Example
|desc=If six monitors were to be attached to a computer, peripheral.find("monitor") would return their handles in that order: Bottom, top, back, front, right and left.
That order always stays the same. The bottom peripheral will always have the priority and be returned first.
peripheral.getNames() follows the same return pattern. It could be used to find out the order in which the peripheral handles will be returned when using peripheral.find().
|code= local bottomMonitor, topMonitor, backMonitor, frontMonitor, rightMonitor, leftMonitor = '''peripheral.find("monitor")'''
textutils.tabulate(peripheral.getNames())

|output= Will print the string 'bottom top back front right left' on the terminal.
