To illustrate an example, let us assume that the font you need is "Laser Chrome".
Use Google to find a font download site, or to do a search for "Laser Chrome" using the parentheses. Google also has an easy to use "Advanced Search". Type Laser Chrome where it allows for "Exact Phrase" at the Google Advanced Search site. Then where it allows for "All of the Words" type Font.
I used Google to find:
http://www.fontsforsale.com/Laser_Chrome.htm
http://fonts-free.com/font/laser-chrome.html (free download)
http://www.itcfonts.com/fonts/detail.asp?nCo=AFMT&sku=ITC2219
and Google has lots of URLs all about this font.
Fonts
need two files to work: one file will not work without the other file
and by going to a font download site, its all done automatically.
Windows Users: All you
have to do is to install the font through Settings/ControlPanel/Fonts
then click on File, Install New Font.
