Its free to view and read but apparently we have to pay £5 if we want to print it without the DO NOT PRINT written in the file.
I think they are a bit naive if they believe that! As good boys and girls I know you will only read it and not print it without paying £5...
The PDF is locked for printing, you don't think they would trust people to pay £5 if the option was there to print do you?
Although it is trivial to remove these sort of restrictions / watermarks from secured PDF's if you know how to... but i'm not sure of the legalities in doing that...
