Printing file name with document

How can I print the file name together with the printed document?

My Product Information:
Acrobat Pro 8.0999999999999996447286321199499070644378662109375, Windows 2007-11-08 11:50:44 Registered: Sep 24 2005

You can find this option under File / Print / Advanced / Mark and Bleeds / Page Information. This will take the file name and automatically place on the output.

If you want more control then use the Document / Add Header / Footer command (or indeed any of the ones in the top category) ..

I've been using Acrobat since v1.0 and still get amazed by its power. An Acrobat ACE since 1999

I have tried this but. 'File / Print / Advanced / Mark and Bleeds / Page Information'. Is greyed out, not allowing me to make any changes. Any ideas why?

I've also tried adding 'headers' with the file name but it appears over the image area, I need it to appear at the top, outside the image area.

Its driving me nuts, any help would be greatly appreciated!!
