  I got it working but there must be a simpler way to achieve this.

      console.log( ' selectedPrintData = '+ JSON.stringify(selectedPrintData));
      newSelectedPrintData = [selectedPrintData];
      console.log( ' newSelectedPrintData = '+ JSON.stringify(newSelectedPrintData));
      var inv_list = selectedPrintData.data;
      console.log( ' inv_list = '+ JSON.stringify(inv_list));
  
      for (var i = 0; i < inv_list.length; i++) {
          doc.text(5,rowPos,inv_list[i].inv_list.quantity);
       }
  

  [Log]  selectedPrintData = {"data":[{"DT_RowId":"row_10120","inv_list":{"lineID":"10120","InvID":"3113","quantity":"100","barCode":"5555","stockCode":"8686856rrr","size":"77","colour":"ref","description":"Big drill massifffffh","costPrice":"0.00","sellPrice":"10.00","lineTotalNett":"1000.00","lineTotal":"24.00","vatRate":"20.00"}}],"options":[],"files":[]} (code.js, line 1352)
  
   newSelectedPrintData = [{"data":[{"DT_RowId":"row_10120","inv_list":{"lineID":"10120","InvID":"3113","quantity":"100","barCode":"5555","stockCode":"8686856rrr","size":"77","colour":"ref","description":"Big drill massifffffh","costPrice":"0.00","sellPrice":"10.00","lineTotalNett":"1000.00","lineTotal":"24.00","vatRate":"20.00"}}],"options":[],"files":[]}]
  
   inv_list = [{"DT_RowId":"row_10120","inv_list":{"lineID":"10120","InvID":"3113","quantity":"100","barCode":"5555","stockCode":"8686856rrr","size":"77","colour":"ref","description":"Big drill massifffffh","costPrice":"0.00","sellPrice":"10.00","lineTotalNett":"1000.00","lineTotal":"24.00","vatRate":"20.00"}}]

  "What is the correct way to get thhe returned data into an array then be able to alert the 'quantity' value."

  the data is alredy in an array (of objects): json.data

  $('#dtInvoiceDetails')
     .on('xhr.dt', function ( e, settings, json, xhr ) {
            alert(json.data[0].quantity)
     } );  
  

  or something like this

  $('#dtInvoiceDetails')
     .on('xhr.dt', function ( e, settings, json, xhr ) {
           for (i=0; i < json.data.length; i++) {
               alert(json.data[i].quantity)
           }
     } );
