Corrected entry: Data takes a holographic paper off the holodeck.
Corrected entry: When Data hands Geordi the paper with the image of the Enterprise on it, Geordi looks at the picture then turns it over. However, when he flips the picture it is the right way up, so it means that Geordi has been looking at the picture upside down.
Correction: Geordi is intimatly familier with the Enterprise. He can recognize it no matter how it is oriented.
Correction: It is often explained that the holodeck uses a combination of holographic projection, transporter, and replication technology to achieve its illusions. This is why people on the holodeck are able to eat food created there. Something like paper would be easily replicated as real and so could leave the holodeck. Living beings are much more complex.
