If both POS & Manager are both open the receipt won't print & we get error: "Invaid Operation 425: The printer cannot be accessed. It may be locked by another application."
Printer sharing is checked in configuration in Manager. Runing OPOS driver on the Ithaca. Running Windows XP.
We run only one terminal & have to close Manager to check out every customer.
Have updated the driver to OPOS version 1.6 per tech support instructions - problem persistw
