The easy answer is that if you don't know what they are, probably not. If
you have a postscript printer and you want to print usiung postscript fonts,
these are necessary. These are specialf fonts commonly used in the
publishing world. If all you are using is Times New Roman, Arial, etc.., I
guess they are really just taking up space.
You might want to review the features of your specific printer, see if it
prints postscript fonts, and determine if printing with postscript fonts is
something you ever want to do.
