to see that the barcode data is there. PDF is a sort of mangled Post
Script stream.
Below is the stream for a single item. The line with the series of
zeros and ones is the barcode. However, I can confirm that the
barcodes do not display in Reader 9.0 while they do in 7.0. Versions
8.0 and 9.0 use PDF version 1.7 while 7.0 uses 1.6. There may be a
subtle difference in syntax that causes the breakage. I'll open a bug
and try to take a look at it next week.
