Identifying Symbol Content
To identify content or "format" aspects of a symbol, 2D PQA modes report the
less than obvious characteristics of a symbol. For quality determination, 2D
PQA reports those parameters that both relate directly to the print or creation
process, and that also remain relatively consistent over a range of hand held

message similar to the following (with slight variations based upon the symbol-
ogy being tested):
