Displaying /printing a pdf file from website?

Hi,

I need to upload a form to my website, and then have a link or button to allow users to print it off.

The form doesnt change.

I cant quite work out how to do it so there are as few clicks for the user as possible.

Also not sure, if I put a link in via a text insert, how to reference the location of the file on the website.

What i would really like is it prints out as soon as the link is pressed, but I guess it is always going to stop at the print dialog stage if not before.

Does anyone have any pointers? I do feel I am being a bit dim about it!
