All I can tell you is what happens when I don't use pre-printed labels.
Change tapes
update slots, label barcodes
a random tape is not recognized
do no tape change, take out magazine, reinsert tape in magazine
update slots
tape recognized
This only happened with home made labels. Maybe I should run another month
to make sure, but this is what I see.
