Case

Print your own ZPL labels

Proposed solution

  • You want to print ZPL labels from the mobile device
  • You must generate the needed ZPL yourself
  • You do not want to use the integrated Cloud Print Service solution

How-to: Create custom Unplanned function


Step 1: Create Header

Add the following code to create your new header.

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddHeaderConfigurations', '', true, true)]
    procedure MyOnGetReferenceData_OnAddHeaderConfigurations(var _HeaderFields: Record "MOB HeaderField Element")
    begin
        with _HeaderFields do begin
            // Header Name
            InitConfigurationKey('MyPrintLabelHeader');



            // Input fields on the label
            Create_TextField_ItemNumber(10);
            Create_TextField_LotNumber(20);
            Create_DateField_ExpirationDate(30);
            Create_IntegerField_Quantity(40);

            // Printer list
            Create_ListField(50, 'Printer');
            Set_label('Printer:');
            Set_listValues('Printer A IP;Printer B MAC');
            Set_clearOnClear(false);
            Set_acceptBarcode(false);

            // Number of Labels
            Create_IntegerField(60, 'NumberOfLabels');
            Set_label('Number of labels:');
            Set_clearOnClear(true);
            Set_acceptBarcode(false);
            Set_defaultValue(1);
            Set_minValue(0);
            Set_maxvalue(10);
        end;
    end;

 

Step 2: Modify mobile config

You need let the Mobile configuration know that your new function and header is available.

Add the following to the Mobile Configuration Files to create a new page, a main menu icon as well as an action 


  • Define a new Unplanned Function -page

    <page id="MyPrintLabel" type="UnplannedItemRegistration" icon="mainmenucount-unplanned">
  <title defaultValue="My print label page"/>
  <unplannedItemRegistrationConfiguration type="MyPrintLabel" useRegistrationCollector="false">
    <header configurationKey="MyPrintLabelHeader"/>
  </unplannedItemRegistrationConfiguration>
</page>

  • Add Icon to main menu for the unplanned function

    <menuItem id="MyPrintLabel" displayName="MyPrintLabel" icon="mainmenuprint" alwaysEnabled="true"/>

  • Add action to context menu. We use Receive.

    ...</orderListConfiguration>

<actions>
    <open id="MyPrintLabel" title="Print my labels" icon="mainmenuprint"> </open>
</actions>

Step 3: Handle posting / Generate ZPL

When the Header has been accepted a final request is made to "Post" the information ("PostAdhocRegistration").

In this step you must read the collected values and create the ZPL.


   [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Adhoc Registr.", 'OnPostAdhocRegistrationOnCustomRegistrationTypeAsXml', '', true, true)]
    procedure OnPostAdhocRegistrationOnCustomRegistrationTypeAsXml(var _XMLRequestDoc: XmlDocument; var _XMLResponseDoc: XmlDocument; _RegistrationType: Text; var _RegistrationTypeTracking: Text[200]; var _IsHandled: Boolean)
    var
        Item: Record Item;
        TempHeaderFilter: Record "MOB NS Request Element" temporary;
        MOBToolbox: Codeunit "MOB Toolbox";
        MobWmsLanguage: Codeunit "MOB WMS Language";
        MobRequestMgt: Codeunit "MOB NS Request Management";
        XMLResponseData: XmlNode;
        Status: Text;
        PrintCommand: Text;
        LotNo: Text;
        ItemNumber: Text;
        Printer: Text;
        PrinterAddress: Text[50];
        ExpirationDate: Date;
        Quantity: Decimal;
        NoOfLabels: Decimal;
    begin
        if _RegistrationType = 'MyPrintLabel' then begin



            MobRequestMgt.SaveAdhocFilters(_XMLRequestDoc, TempHeaderFilter);

            // Read the request field values 
            ItemNumber := TempHeaderFilter.GetValue('ItemNumber');
            LotNo := TempHeaderFilter.GetValue('LotNo');
            Printer := TempHeaderFilter.GetValue('Printer');
            Quantity := TempHeaderFilter.GetValueAsDecimal('Quantity');
            NoOfLabels := TempHeaderFilter.GetValueAsDecimal('NoOfLabels');
            ExpirationDate := TempHeaderFilter.GetValueAsDate('ExpirationDate');

            Item.Get(ItemNumber);

            // Generate your ZPL
            PrintCommand += '^XA';
            PrintCommand += '^FO50,50^ADN,54,30^FD' + Item.Description + '^FS';
            PrintCommand += '^FO50,130^BCN,100,Y,N,N^FD' + ItemNumber + '^FS';
            PrintCommand += '^FO50,280^ADN,54,30^FDQty: ' + FORMAT(Quantity, 0, 9) + '^FS';
            PrintCommand += '^FO50,380^ADN,54,30^FDExp: ' + FORMAT(ExpirationDate, 0, 9) + '^FS';
            PrintCommand += '^FO50,500^ADN,54,30^FDLOT: ^FS';
            PrintCommand += '^FO200,470^BCN,100,Y,N,N^FD' + LotNo + '^FS';
            PrintCommand += '^PQ' + FORMAT(NoOfLabels) + ',0,0,';
            PrintCommand += '^XZ';

            // Convert printer name to a network address 
            case Printer of
                'Printer A IP':
                    PrinterAddress := '1921681010';
                'Printer B MAC':
                    PrinterAddress := '00225832FDAB';
            end;

            // Create print response to mobile device
            MOBToolbox.InitializeResponseDocWithDesc(_XMLResponseDoc, XMLResponseData, MobWmsLanguage.GetMessage('PRINT_RESPONSE'));
            MOBToolbox.AddZPLPrintCommandToRequest(XMLResponseData, PrinterAddress, PrintCommand);

            Status := 'OK';
            _IsHandled := true;
        end;
    end;

 

Step 4: Respond with ZPL

The mobile device will issue the print.

The XML response should look like this:

<?xml version="1.0" encoding="UTF-8"?>
<response xmlns="http://schemas.microsoft.com/Dynamics/Mobile/2007/04/Documents/Response" messageid="89CF29D1-941A-4459-8767-B83203C67355" status="Completed">
  <description>Print OK</description>
  <responseData xmlns="http://schemas.taskletfactory.com/MobileWMS/BaseDataModel">
    <print xmlns="">
      <printerType>Zebra</printerType>
      <printerAddress>1921681010</printerAddress>
      <printCommand>^XA^FO50,50^ADN,54,30^FDIntense Orange^FS^FO50,130^BCN,100,Y,N,N^FDtf-002^FS^FO50,280^ADN,54,30^FDQty: 1^FS^FO50,380^ADN,54,30^FDExp: 2020-03-24^FS^FO50,500^ADN,54,30^FDLOT: ^FS^FO200,470^BCN,100,Y,N,N^FD^FS^PQ0,0,0,^XZ</printCommand>
    </print>
  </responseData>
</response>
