Receipt creation

WDePOS-Create-Receipt.swift

//We assume you have complete a Sale or retreived a Sale Response using History query/search. 
//Note: having a valid Sale Response object is mandatory for the steps below.

let saleResponse: WDSaleResponse = WDSaleResponse() //In your code, instead of an empty sale, saleResponse is your actual sale response object

//Receipt for individual payments:
//If you want the receipt for a payment you know its id (instead of the whole Sale), you can get the saleResponse of that subPayment by using the function:
//let subPaymentResponse = saleResponse.paymentForReceipt:yourPaymentId
//subPaymentResponse.receipt(:showReturns:format:...

saleResponse.receipt(true, //Is the receipt for cardholder use? For more details, see documentation above
    showReturns: false, //Should the receipt contain returns?
    format: WDPrintFormat.datecs, //The receipt format (in this case, for portable Datecs, but could be PDF, html, etc.)
    dpi: WDPrintDpi.default, //The dots per width is set to Default - valid for Datecs or AirPrint
    completion: { (receipt: Any?, error: Error?) in

                 //For more details on printing receipt, see the Printer Manager section
            
    })

//Note: Other variations of the function above are offered to you for choosing the language and locale of the receipt content.
