How to add Printer lookup in AX 2012

1. Create a class or add below method to use it globally:

Class printers

{

}

//This method loads all available printers to a Map object 

static Map printerMap()

{

    Microsoft.Dynamics.AX.Framework.Reporting.Shared.PrinterHelper printerHelper;

    Microsoft.Dynamics.AX.Framework.Reporting.Shared.PrinterInfo printerInfo;

    System.Collections.ArrayList names;

    System.Collections.IEnumerator enumerator;

    Map         printerMap;

    str name;

    int printerStatus;

    str driverName;

    str portName;

    str comments;

    int jobCountSinceLastReset;

    if(!printerMap)

    {

        printerMap = new Map(Types::String, Types::Container);

        // BP Deviation documented

        printerHelper = new Microsoft.Dynamics.AX.Framework.Reporting.Shared.PrinterHelper();

        names = printerHelper.get_PrinterNames();

        if (names != null)

        {

            enumerator = names.GetEnumerator();

            while (enumerator.MoveNext())

            {

                name = enumerator.get_Current();

                printerInfo = printerHelper.GetPrinterInfo(name);

                // BP Deviation documented

                printerStatus           = CLRInterop::getAnyTypeForObject(printerInfo.get_PrinterStatus());

                // BP Deviation documented

                driverName              = CLRInterop::getAnyTypeForObject(printerInfo.get_DriverName());

                // BP Deviation documented

                portName                = CLRInterop::getAnyTypeForObject(printerInfo.get_PortName());

                // BP Deviation documented

                comments                = CLRInterop::getAnyTypeForObject(printerInfo.get_Comment());

                // BP Deviation documented

                jobCountSinceLastReset  = CLRInterop::getAnyTypeForObject(printerInfo.get_JobCountSinceLastReset());

                printerMap.insert(name, [name, printerStatus, driverName, portName, comments, jobCountSinceLastReset]);

            }

        }

    }

    return printerMap;

}

2. Build lookup Method

public static void printerLookup(FormControl _formControl)

{

    SysTableLookup                  sysTableLookup;

    TmpTableFieldLookup             tmpTableFieldLookup;

    Enumerator                      en;

    List                            entitylist      = new list(types::String);

    Map                             printerMap;

    MapEnumerator                   enumerator;

    PrinterName                     printerName;

    printerMap          = printerMap();//If above method was created in Global class else call specific class 

    enumerator          = printerMap.getEnumerator();

    while (enumerator.moveNext())

    {

        printerName = enumerator.currentValue();

        entitylist.addend(printerName);

    }

    en = entityList.getEnumerator();

    while (en.moveNext())

    {

        tmpTableFieldLookup.TableName = en.current();

        tmpTableFieldLookup.insert();

    }

    sysTableLookup = SysTableLookup::newParameters(tableNum(tmpTableFieldLookup), _formControl);

    sysTableLookup.addLookupfield(fieldNum(TmpTableFieldLookup, TableName));

    sysTableLookup.setLabel("@SYS62708");

    //BP Deviation documented

    sysTableLookup.parmTmpBuffer(tmpTableFieldLookup);

    sysTableLookup.performFormLookup();

}
