There's more than one way to print only part of a web page but I must say
that this free web service is one of the better choices as there is nothing
to install. One of our site visitors commented that it can be combined with a
PDF printer to produce a PDF of only part of a page. I haven't tried that but
if it works it's a nice bonus.
