We are running Windows 7 64 bit using an Epson TM-T88IV receipt printer connected to the LPT1 port with a cash drawer daisy chained to it. We are using OPOS drivers version 2.5 SP10 and Dynamics RMS version 2.0.
We have an external program that needs to print to the Epson printer and it functions normally when POS is closed.
When we try to use the program with POS running we get an error about file/path access. The "share OPOS printer" option is selected in Manager and normal functionality works as far as printing receipts and opening the cash drawer. It seems that the cash drawer is preventing the OPOS printer from actually being shared with the external program causing the file/path access error.
This same setup worked just fine on our old Windows XP machines running the same versions of OPOS and Dynamics RMS.
Has anyone been able to solve this?
