Probably the most friendly file format would be PDF.  First convert your
file to PDF format.  Most folks here like the freebee, Primopdf and you can
get it at:

www.primopdf.com

To keep your website files on the server orderly I recommend you create a
new folder, i.e., downloads.

Lets call your new file good_stuff.pdf     (note no spaces or uppercase)

Upload your newly created good_stuff.pdf file into the downloads folder.

On your website page you will need to add the link to the good_stuff.pdf
file.

Use any word/s or image for your link; something like

Get the information on Good Stuff, click here.

Capture the word here with the mouse and then do Insert, Hyperlink

and put in the box

/downloads/good_stuff.pdf

OK

Save the new website and upload it in the normal way.

Check you work by bringing up your website and clicking on the underlined
word,  here.

Your good_stuff.pdf file should open up for reading, and or saving.

As Don says, a pdf version will work. But what are you wanting visitors
to print? An entry form, for instance. If so, I create a new page, with
just the form on it and add an HTML code fragment that has this in it:
<input type="button" name="print" value="Print Form"
onclick="javascript:window.print();">
