P-Pen / Print touch pen

Concept
I got an idea from the polaroid camera which can take the analogue
moment of daily life and experience. People want to post their daily
life on their homepage. However, they also want to record it into picture
diary like they did when they were child.

How to use

P-PEN is a touch-pen which can transfer picture from electrical devices and
print it. Normally, you can use it as a touch-pen. When you need to print
something, just draw the line around the picture that you want to print.
Pull each side of the pen which is look like a wheel. Then, roll the pen with
your hand on the paper. You will get the picture on the paper.
