Problem: When I have the HP A794 thermal printer connected and a 2nd printer(Brother Fullpage printer) is connected to the computer store operations POS will not open. I do not have the brother configured inside RMS, it is configured in windows only. When POS does not open I have to close it from task manager. The only way I can get POS to open is to open manager first and then open POS. Any other way will not work.
I took the brother printer out of the equation and everything works fine with just the A794 plugged in. The A794 is running on a OPOS driver.
Any suggestions ? I am pretty sure it is having COM conflicts, but not sure how to approach the problem.
Thanks guys !
