If this teleportation system exists, why would anybody want to tie it in with the artistic abilities of the customers?
Instead of a magic pen, why not have a magic microphone? You speak into it and tell it the name of the food you want and that food gets teleported to you.
So you start by drawing another magic pen. Now the marginal cost of each pen is nearly zero, and so unless the owner wants to deliberately restrict it, very quickly everyone will have one. And if the owner does want to restrict it, he won’t be able to sell it for any price, or it’ll eventually end up in the hands of someone who doesn’t want to restrict it.

Sorted.
Never underestimate the lengths rights-holders will go to in order to defend their artificial scarcity. See also Terminator Seeds.
They have that at my local Sonic…
The best solution I have is edible inkand rice paper. Probably not a lot of flavor variation, but then the OP didn’t ask for that.
What about us southerners? I mean, I do work up an appetite cursing out google on my handset but I don’t want chit’luns when I distinctly asked for chicken.
Does this pen require batteries?
Here’s a demo of the 3Doodler, a 3-d pen. 3Doodler 3D Printing Pen Kickstarter Video - The World's First 3D Printing Pen (Official) - YouTube
Make the “ink” edible and flavored, and rake in the money! 
You really could make a pen that draws hot sugar syrup that cools instantly. So you draw on an oiled metal sheet your caramel sugar drawing, and then pop it off.
OK, I just did some googling, and it turns out this is already a thing. Only difference is this guy uses a spoon rather than a pen, but still.
Is this where “drawn butter” comes from?
<Morbo>REALITY DOES NOT WORK THAT WAY</Morbo>
I read a book all about this. They made a documentary out of the book called Harold and the Purple Crayon (YouTube 4:55).
ETA: This magic pen can create anything at all… but go to 1:58 to see the food being created.
<draws a copy, not of itself, but of the original pen>
Ever notice how easy it is to circumvent copy-protection?
Maybe require that the pen has an always-on internet connection to verify registration? And if it loses the connection, your dinner crashes.
How about a menu with pictures of food. You point at the pic you want, soon it shows up on the table. This technology exists. It’s called a restaurant.
Bah. I can speak to a person remotely using electricity and the food i desire appears at my door. My takeaway laughs at your puny human ‘restaurant’.
What if you don’t know what the original looks like? If there’s only one, or the few there are happen to be tightly controlled, you don’t know what little piece you need.
That goes back to the original objections of the rather simplistic hypothetical: how does the pen know what I’ve really drawn? In this case, the copy-protection-defeating characteristics Chronos proposes would be hard for The Magic Pen to understand, just from being drawn. In a manner as fundamental as someone drawing an apple and getting a tomato.
Though Chronos is right in principle: copy protection and counter-measures are a constant chess game. In any kind of magical post-scarcity environment (like The Magic Pen), enforcing artificial scarcity is difficult. Probably impossible, from a technical perspective, against a determined circumventor.
modest hijack,
this is truly terrifying and a terrible as ideas go, to me.
I now return you to your regularly scheduled thread.
