3.    Set Sales as the Type of Voucher.

5.    Set Use for POS Invoicing? to Yes.

Note: The Use for POS Invoicing? option will appear only when the Default Tax Unit is set to Not Applicable.

6.    Enter Print Message 1 and Print Message 2, as required. You can enter any custom messages (such as "Thank You" or "Visit Again"), which will be printed at the bottom of the POS invoice.

7.    Enter the Default Print Title, as required.

8.    Press Enter to skip the Name of Class.
