Subj: BAR CODE BOOK
I'm trying to research your question on the 'Z'. Meanwhile, I obtained a copy of "THE BAR CODE BOOK Reading, Printing and Specification of Bar Code Symbols" By Roger C. Palmer. It has got to be the most comprehensive book on all bar codes that I have ever seen, and it just appeared on the local 'Half Price Books' shelf! The ISBN is 0-1911261-05-2 (paperbound), and the publisher is Helmers Publishing, Inc. 174 Conord Street Peterborough, NH 03458. I really suggest you acquire this book if at all possible. My hunch regarding 'Z' at first guess is related to a timing sequence between the bars. I'm going to try and ferret out an explanation for you if I can decipher all this technical info in the book.
