SubGrid header in printView

Hello
I have grid with subgrid and displaying subgrid without header

grid.attachEvent("onSubGridCreated",function(sub,rId,rInd){
    sub.setNoHeader(true);
    return true;
)}

But when I call grid.printView(), I get subgrid but with header!

How can i get rid of subgrid header in printView? Or else print grid as I have?

Thank you for answer
