Ok, a few things to note:

1. Don't post giant walls of code. Even in code tags ( [.code] , Without the . )
Use Pastebin instead
I've uploaded it for you, correctly indented:
http://pastebin.com/idrqk0vg

2. Indent!

3. What is your question? The title, 'Not Printing On Screen "MC"' isn't very clear

"mc" is a wrapped monitor. You might write to it on lines 37 or 42, but then you don't pause at all before the loop flies back around to line 26, which clears whatever might've been there… So good luck seeing it. :P/>

sorry for not being clear this is the paste bin http://pastebin.com/cWHKPqUJ# and it is on line 32 - 44

Your entire code is one big mess. You are defining a function inside a while loop? What are you trying to archieve there?

I recommend structuring your code like most people:
First your variables, then your functions, and at the end your main code/loop.
I also recommend giving your variables descriptive names, so the code is easier to read. "mc" isn't really descriptive, is it?

Your actual problem is hard to find because of the mess, but you're probably writing something to the monitor and then you immediately clear the monitor, like Bomb Bloke said:

sorry i couldent use

it screwed it up

What do you mean "that screwed it up"? Try uploading the code to pastebin.

And you're still defining the airLock function inside a while loop, and everything is still a mess. Did you actually change anything?

it only prints on the monitors when i break the loop

No, it always printed on the monitor - you just cleared the monitors off again so quickly that it was impossible to see.

so what do i change

Truth be told, I was mistaken - later edits of your script will fail to write to the monitor, due to the changed scope of your "al" variable - you can't reference a local variable before you declare it as local, which you ended up trying to do by moving the airlock() function upwards! But my original point still stands.

See, it's basically just a case of implementing a delay in between when you write to your monitor, and when you clear it off again.

io.read() provides a decent delay, so how about you call airlock() just before that, instead of just after it? That way, what it writes will be visible so long as the system is waiting for the user to type something - when they hit enter it'll be cleared off, and near-instantly re-written again (perhaps with a new value). That way the text should be visible pretty much all the time, as opposed to how you've been doing things, where it's visible pretty much none of the time.

Just for kicks, here's a quick clean-up of the code:

local tr = peripheral.wrap('BigReactors-Turbine_1')

-- These two peripherals aren't used yet?

	mc.clear()
	mc.setCursorPos(1,1)
	if rs.getInput("left") then mc.write("Sealed") else mc.write("Unsealed") end
	
	write("Enter command (? for help): ")
	local input = io.read():lower()  -- Convert the result of the read command to lowercase to make matching simpler.
	
	if input == "restart" then
