So check your page number (which I assume is based on NumberOfItemPrintedSofar) and only print the header on the first page.

And do yourself a favour: don't create Font objects willy nilly - they each use Handles which are scarce resources that are only released when the Font object is Disposed. And just creating new instances all the time will run you out of Handles long, long before your run out of memory and the GC kicks in to automatically dispose them.

Create one sample of each font you use - and from what I can see you only need two - and keep them in class based private variables - your code will be faster, and won't crash with "out of memory" errors when the Handles are exhausted.
