❗ By default bill printing works by printing to .pdf file in PrintOuts folder located in bin/Debug or bin/Release this may ❗ NOT work if you do not have Microsoft Print to PDF Printer installed. Edit Config/Receipt.cs PrinterName and disable PrintToFile or install Microsoft Print to PDF if that is the case.

❗ By default the program uses localhost as the ip for DB and also uses windows authentication. Edit connection string in App.config if needed.
