How can you spot the difference between a robot written letter and a printed one?

And what about volumes, is each letter has different text? Should have slightly different writing?

Or are there some volumes in the system?

There are variations in pressure that are really easy to recognize.

Not sure I understand the second question.

Edit: Do you sometimes print the same letter(or a templatized letter) 100/1000 times ?

This would have been a good optimization but we did not. Every letter generated was unique even if it was a templatized piece.
