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: Post on Posting Warehouse Receipts

Step 1: Add printer steps on posting

In order to determine when, where and what to print, we add a step on posting

Add the following code to create a step on posting.

See also: How-to: Add Header Step

    // 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 Receive", 'OnPostReceiveOrder_OnAddStepsToAnyHeader', '', true, true)]
    localprocedure OnPostReceivekOrder_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 Receipt Header"]) thenbegin// This example is limited to Whse. Receipts

           // 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 print');
            _StepsElement.Set_listValues(' ;' + MobPrint.GetMobilePrinters('Item Label 3x2', '')); // 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 steps on posting to issue print

    // 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 Receive", 'OnPostReceiveOrder_OnAfterPostAnyOrder', '', true, true)]
    localprocedure MyOnPostReceiveOrder_OnAfterPostAnyOrder(var _OrderValues: Record "MOB Common Element"; _RecRef: RecordRef; var _ResultMessage: Text)
    var
        MobPrinter: Record "MOB Printer";
        TempPrintParameter: Record "MOB Print REST Parameter" temporary;
        MobPrint: Codeunit "MOB Print";
        MobPrintBuffer: Codeunit "MOB Print Buffer";
        PrintCommand: Text;
    begin
        // Did user select a printer, else exit
        ifnot _OrderValues.HasValue('Printer') then
            exit;

        // Init printer parameters
        Evaluate(TempPrintParameter.Printer, _OrderValues.GetValue('Printer')); // Printer selected
        TempPrintParameter."Label-Template Name" := 'Item Label 3x2'; // The label to print - consider making this configurable
        MobPrint.SetSourceRecRef(_RecRef);
        MobPrint.SetRequestElementsFromOrderValues(_OrderValues);

        if MobPrint.Run(TempPrintParameter) thenbegin
            // Print was is returned from cloud
            TempPrintParameter.GetResponseContentAsBase64Text(PrintCommand);
            MobPrint.GetPrinterFromName(MobPrinter, TempPrintParameter.Printer);
            MobPrintBuffer.Add(MobPrinter.Address, PrintCommand);

        endelse
            // If failed, append Error to ResultMessage
           _ResultMessage := _ResultMessage + ' Print failed: ' + GetLastErrorText();

    end;

Example 2: Post on Posting Warehouse Picks

    // 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 print');
            _StepsElement.Set_listValues(' ;' + MobPrint.GetMobilePrinters('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.');also select a blank printer
        end;
    end;

The example code is for receive.

Select another event if you are working with another function.

Filter by label (Content by label)showLabelsfalsemax150showSpacefalsesorttitleexcludeCurrenttruecqllabel = "integrationevent" and label = "onaddstepsto" and label in ("order","orders")    _StepsElement.Set_helpLabel('If you want a label, please select a printer.');
        end;
    end;

Step 2:  Handle steps on posting

to issue print

    // Step 2: Handle Header step and issue print
        //  We read the collected step 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   Issue a print based on printer, label and the current context (Order Header)

        MobPrint        MobPrint.SetRequestElementsFromOrderValues(_OrderValues);
        // Perform cloud print

            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
