[IUG] Receipts not printing every time

["Welch, Andrew" <AWelch at auroragov dot org>]

We're having an issue with our receipt printers at the circ desk. When
items are checked out to a patron and staff click the Close button, the
receipt doesn't always list the patron's items, just the "Items checked
out to..." message at the top and our custom message at the bottom.
However, clicking the Print button before closing the patron record
prints the receipt correctly every time. Of course, this means a huge
waste of receipt paper, as we often get 2 full receipts for each
transaction.

The really odd thing is that receipt printing is working perfectly at
our Central branch, which sees by far the highest volume. Nearly every
one of our 6 other branches reports the above problem. To make matters
worse, it isn't at all consistent (that we can tell); not tied to
specific patrons or item types or a particular time of day. This makes
us wonder if perhaps it's a network issue, but we can't see why receipt
printing would need to talk to the Millennium server when the
information it needs is already sitting in the patron window.

Has anyone else experienced this and determined a cause?
OR
Can someone confirm whether the network is involved in the "Close"
method of receipt printing?
OR
Is there an option to only use the Print button and turn off the Close
button for receipts?

Thanks!
