Method and system for reproducing identification characters
First Claim
1. A method of reproducing identification characters from a first substrate on a second substrate that are both man and machine readable using a dot matrix printer and an optical character reader comprising the steps of:
- scanning the characters on said first substrate with said optical character reader to obtain information as to said identification characters,transmitting said information to control said dot matrix printer in accordance with said information on said first substrate to form characters of a matrix of dots, at least some of which overlap, so that said characters have apparent solid lines that are capable of being read with an optical character reader.

Abstract
A method and system are described for producing identification characters that are both man and machine readable. The identification characters, such as those on a patient'"'"'s I.D. bracelet or an inventory control tag, are scanned with an optical character reader. The character information obtained from the reader, or other input source, is processed and used to control the reproduction of the identification characters using a dot matrix printer. The readability of the characters is enhanced by using thermal paper and increasing the heat applied by the dot matrix printer to (1) enlarge the area of the dots and (2) increase their optical absorbance. The increased area and absorbance produces an apparent solid line character which is more easily readable by an optical character reader.
