Barcoding new 14 char UPC

As of Jan 1st 2005, I believe there was an industry change with the
length of the UPC code, allowing 13 or 14 digits.

Has anyone conformed to this new standard with printing?  I'm not sure
how to do it.
 
I found a thread talking about this new compliance:
http://archive.midrange.com/midrange-l/200407/msg00470.html
 
... but the answer there is to conform to scan the new length, but not
to conform to printing it as such.  We need to reproduce the UPC to put
it on the package when we send it out, so we do need to print a 13- or
14-digit UPC.
 
Looking at:

I wonder if Table 1 has something I can use, or does IBM need to supply
a new valid bar code definition?
 
Any help would be appreciated.
Thanks,
