You are attempting to use version 3.0 options in version 2.2.  Looking
on page 781 of the 2.2 mathematica book, I see that Display does not
support different file types.  It only displays in a specialized
postscript format.  I think this means you won't be able to print
graphics directly from anything but a postscript printer.  

You really need documentation(ie, an appropriate Mathematica book) to be
able to get anything done in mathematica.  If you can't find one (since
I doubt wolfram is selling 2.2 mathematica books anymore), I recommend
getting in the habit of typing ??command on any commands you get error
messages on.  In the question above, ??Display would have clued you in
on what options were supported in 2.2.
