Hello indyptech
As far as I can understand your problem is terminals shares same printing configuration.
For your need we need to seperate them and configure each terminal individually for bill printing.
For example you have cash1, cash2 terminals:
1. Create "Cash1" and "Cash2" terminals from "Terminals" menu.
2. Walk in front of Cash1 computer and choose "Cash1" from "Local Settings". Do the same for the other but choose "Cash2" as Terminal. Now each computers physically use different terminal settings. You can do the rest from any computer.
3. Create two printers from "Printers" menu. "Cash1 Printer" and "Cash2 Printer"
4. Create two print jobs and name them as "Print to Cash1", "Print to Cash2" and map them to related Printers.
5. For "Cash1" terminal choose "Print to Cash1" Print Job and for "Cash2" terminal choose "Print to Cash2" Print Job. Dont forget to choose other needed print jobs such as Kitchen printing.
Now each cash should use their own printer.
