We just moved our shipping operations onto a windows 7(64) platform.
This include a USB Eltron 2844 label printer for our UPS operations.

Our mainstay application is browser based, and prints UPS labels to this
printer by downloading a .EPL file, which is then copied to the printer
with a simple batch file.

Attempting to print a single label results in printing two to seven
DIFFERENT labels, all valid labels, originally printed within the last
24 hours or so, along with AT THE END OF THE PRINTING, the one label we
wanted. After trying in vain to determine what was wrong with the
application, and not finding any data in that EPL file other than that
for the one label I want, I tried a simple experiment:

I modified the batch file that copies the EPL file to the printer so
that after it does so, it pauses, then prints the exact same file to the
exact same printer the exact same way, again.

I do NOT get the same results. Each print job consists of a different
amount of labels, all valid UPS labels, all different, along with the
one label that is actually the entire print job being sent.

copy %1 \\UPSCOMPUTER\UPSLABEL

is the command. The printer is local, but being USB, this appears to be
the only way to get a dos print job to interface with it.

This is the weirdest thing I have ever seen. I have no idea where this
data is coming from.
