I use FireFox and it opens Yahoo automatically as my home page. I have this and other websites bookmarked in Yahoo. I opened the URL that this document is located and there is no book icon that I can see. The location of this document is cardigancorgis.com/NS2017/Premiums/Cardigans.pdf
FireFox IS the browser, its the software on your PC
Yahoo is your homepage and the website you are visiting
Cardigans.pdf is not a webpage
it is a Document stored in PDF format
and then either displayed on your display via a browser plugin OR converted on the fly and sent to you page by page as you scroll
to properly print pages of a PDf file
you need to Download and open the file
and print the pages you want
which you have already learned how to do
"prt sc" may or may not give you a correct print out, of one page at a time
you only have to try, to find out
if you only need a couple pages, it worth trying
if you need the whole thing, there is no shortcut or better method than down loading then printing
"prt sc" is a button on your keyboard
