How to pass out argument of type BarTender.Messages - jacob

Question

I try to integrate Java application with Bartender Seagull ActiveX interface using jacob 1.19 library. I have a problem with print method because I do not know how to call this method from jacob.
I tried following code:
public void print( String printJobName, Boolean waitForSpoolJobToComplete, Integer timeoutMs )
{
Variant args[] = new Variant[ 4 ];
args[ 0 ] = new Variant( printJobName );
args[ 1 ] = new Variant( waitForSpoolJobToComplete );
args[ 2 ] = new Variant( timeoutMs );
args[ 3 ] = new Variant();
args[ 3 ].putNoParam();
Variant ret = format.invoke( "Print", args );
}
where format is a .com.jacob.activeX.ActiveXComponent instance and I get exception:
A COM exception has been encountered: At Invoke of: Print Description:
80020005 / Type mismatch.
I think that Messages argument causes this exception. How to pass this argument?

Not 100% sure of the code as I didn't try the following code. If any Java errors happens, do correct me.
Did a few reading in Help Seagull:
1. Declare BarTender Variables
ActiveXComponent btApp = new ActiveXComponent( "BarTender.Application" );
2. Prepare Format.Print function
//Format.Print: Returns an object of btPrnRslt
public boolean print( String printJobName, Boolean waitForSpoolJobToComplete, Integer timeoutMs, Variant btMsgCol )
{
Variant args[] = new Variant[ 4 ];
args[ 0 ] = new Variant( printJobName );
args[ 1 ] = new Variant( waitForSpoolJobToComplete );
args[ 2 ] = new Variant( timeoutMs );
args[ 3 ] = new Variant( btMsgCol );
Variant result = format.invoke( "Print", args );
//if (btPrnRslt <> btPrnRsltSuccess)
// return false;
//else
// return true;
}
3. Test Run
if (myFormat.print(firstJob, true, timeOutMS, btMsgCol))
//Do something if success
else
//Do something not success
