Print planning calendar from SAPUI5

I am trying to print aplanning calendar but I have some problem in CSS (like position of interval time).

Here is the code in controller

onPrint:function(){
  var $domTarget = this.byId("PC1").$()[0],
  sTargetContent = $domTarget.innerHTML,
  sOriginalContent = document.body.innerHTML;
  document.body.innerHTML = sTargetContent;
  window.print();
  document.body.innerHTML = sOriginalContent;
}

Thanks,

Regards,
