Case

Proposed solution

This examples prints on posting of Warehouse Receipt Lines

• You want to print labels from the mobile device
• You want to use the integrated Cloud Print Service solution
• The label should be printed automatically when posting occurs  

Example 1: Print on Posting Warehouse Pick

    // Step 1: Add Header steps
    // In order to determine when, where and what to print, we add a step on posting
    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Pick", 'OnPostPickOrder_OnAddStepsToAnyHeader', '', true, true)]
    localprocedure OnPostPickOrder_OnAddStepsToAnyHeader(var _OrderValues: Record "MOB Common Element"; _RecRef: RecordRef; var _StepsElement: Record "MOB Steps Element")
    var
        MobPrint: Codeunit "MOB Print";
    begin
        if (_RecRef.Number() in [DataBase::"Warehouse Activity Header"]) thenbegin// This example is limited to Whse. Picks

            // Break when 'Printer' step has been collected to prevent infinite loop
            if _OrderValues.HasValue('Printer') then
                exit;

            _StepsElement.Create_ListStep(1,  'Printer');
                        _StepsElement.Set_header('Label printLabel print');
                        _StepsElement.Set_listValues('   ;'  +  MobPrintMobPrint.GetMobilePrinters('Item Label 3x2', 'Item Label 3x2'));  // Allow user to select blank printer + the printers attached to this labeltemplate
            _StepsElement.Set_helpLabel('If you want a label, please select a printer.');
        end;

    end;

Select the right event

The example code is for receive.

Select another event if you are working with another function.

Step 2:  Handle steps on posting to issue print

    // We read the collected step (printer).
    // Issue a print based on printer, label and the current context (Order Line)
    // Print engine will build a dataset   // Allow user to also select a blank printer
            _StepsElement.Set_helpLabel('If you want a label, please select a printer.');
        end;
    end;

    // Step 2: Handle Header step and issue print
    // We read the collected step (printer)
    // Issue a print based on printer, label and the current context (Order Header)
    [EventSubscriber(ObjectType::Codeunit,  Codeunit::"MOB WMS ReceiveMOB WMS Pick",  'OnPostReceiveOrderOnPostPickOrder_OnAfterPostAnyOrder',  '',  truetrue,  truetrue)]
        local procedure MyOnPostReceiveOrder MyOnPostPickOrder_OnAfterPostAnyOrder(var  _OrderValues:  Record  "MOB Common ElementMOB Common Element";   _RecRef:  RecordRef;  var  _ResultMessage:  Text)
        var
        MobPrinter        MobPrinter:  Record  "MOB PrinterMOB Printer";
        TempPrintParameter        TempPrintParameter:  Record  "MOB Print REST ParameterMOB Print REST Parameter"  temporary;
        MobPrint        MobPrint:  Codeunit  "MOB PrintMOB Print";
        MobLanguage        MobPrintBuffer:  Codeunit  "MOB WMS LanguageMOB Print Buffer";
        MobPrintBuffer:      Codeunit "MOB Print Buffer";
        PrintCommand:   PrintCommand: Text;
        begin
        // -- Prepare to Print
        // Did user select a printer?
        if         // If user selected ' ' blank printer, then exit
        if_OrderValues.GetValue('Printer')   =   '   '  then
                        exit;

        // -- Print
        // Init printer parameters
        Evaluate        // Init printer parameters
        Evaluate(TempPrintParameter.Printer,   _OrderValues.GetValue('Printer'));
        TempPrintParameter// Printer selected
        TempPrintParameter."Label-Template NameTemplate Name"  :=  'Item Label 3x2Item Label 3x2';
        //  Set parameters
        MobPrintThe label to print - consider making this configurable
        MobPrint.SetSourceRecRef(_RecRef);
        MobPrint        MobPrint.SetRequestElementsFromOrderValues(_OrderValues);
        // Perform cloud print
        if MobPrint
        if MobPrint.Run(TempPrintParameter)  then begin
                        //  Command is returned from cloud
            TempPrintParameterPrint was returned from cloud
            TempPrintParameter.GetResponseContentAsBase64Text(PrintCommand);
            // Convert the printer selected to an Address
            MobPrint            MobPrint.GetPrinterFromName(MobPrinter,  TempPrintParameterTempPrintParameter.Printer);
            // Save response to be sent in the next Mobile response
            MobPrintBuffer            MobPrintBuffer.Add(MobPrinter.Address,  PrintCommandPrintCommand);
        
        end else
                        //  If failed, append Error to ResultMessage 
            _ResultMessage := _ResultMessage + ' ' + MobLanguage.GetMessage('PRINT_FAILED') + ': ' + GetLastErrorText();
    end;

Select the right event

The example code is for receive.

Select another event if you are working with another function.

Filter by label (Content by label)showLabelsfalseshowSpacefalsecqllabel = "onafterpost" and label = "integrationevent"If failed, append Error to ResultMessage
           _ResultMessage := _ResultMessage + ' Print failed: ' + GetLastErrorText();
    end;

Step 3: Modify print "Dataset" (optional)

• Use this event to modify the automatically generated dataset

• OnPrintLabel_OnAfterPopulateDataset 
• You can also add custom values to the dataset (you have also created a customized label-template)See also Customize Labels
