The First American EFTPOS Integration will use the printer that's configured in Idealpos for the POS Terminal.
When Idealpos prints out a receipt for a sale that has been paid for using the First American EFTPOS Integration, the sale receipt will include the details from the EFTPOS transaction (i.e. Transaction Approved, the EFTPOS amount, the masked card number and any other ID numbers processed by the EFTPOS terminal).
The printer configuration will vary depending on the type of printer you are using and the interface used (e.g. USB, Ethernet, etc.) to connect the printer to the POS Terminal.
Refer to the Network Printers section in the User Guide for more details on setting up a printer.
