This article requires Mobile WMS Extension version MOB5.23

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  

In this example we will add printing to posting of Warehouse Receipt Lines.

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

Add the following code to create
    // In order to determine when, where and what to print, we add a step on posting.

        var
        MobPrint        MobPrint:  Codeunit  "MOB PrintMOB Print";
        begin
                if  (_RecRef.Number()  in  [DataBase::"Warehouse Receipt Header", Database::"Purchase Header"]) then begin
            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
            Allow user to also select a blank printer
            _StepsElement.Set_helpLabel('If you want a label, please select a printerIf you want a label, please select a printer.');
                end;
      end;

// 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)

        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
