button to convert page to pdf

hi all,


The code bellow works really well, but can any help with making it so it only created pdf on button click. at the moment it converts to pdf on page load, I like a button so users can click it then coverts to pdf and if easy enough convert to word button would be nice as well.
many thanks.
