I know there are a few other threads pretaining to "Invalid Operation 425, Cash Drawer locked by another application" but the solutions given there have not solved our problem.
We have multiple store locations with the exact same set-up but only one is having this problem . The problem happens most of the time but not always.
Our set up is
RMS version 2.0 Printer - Epson Tm-881V Cash Drawer - APG VB320 OPOS ADK 2.6
Running on Windows XP Pro
Any body have an idea?
