In all of the programming projects I've ever done involving printing of bar 
codes, I've only ever used those... mostly code 39, although I used 128 once 
for making very small bar codes, and 2 of 5 for an PO system where the 
vendor specs required that format.

In most cases, I've used some external tool, like a specialized bar code 
printer, to generate the symbols. I did once (about 15 years ago) have to 
write a program to generate code 39 on a laser printer by iterating the 
rectangles myself. I had to copy the spacing out of a book, which was a 
weekend well spent, let me tell you. :D
