Printing a Local Report without Preview

Hi, I need to print some local rdlc reports without previewing it and without any print dialogs. I found a code, that makes it, but however, it creates emf files on disk. I need to make some changes to the code, so that it would work without those files (no files written on disk). The solution with emf files is here: http://msdn.microsoft.com/en-us/library/ms252091.aspx
