Amanda is correct in her reply. An EPS file on the Macintosh has a data fork of 
ascii text - you can open it up with MS Word, QUED, and probably some other
word processors. The one piece of information not mentioned is that when
you do a 'Save As' with some preview, it changes the file type from 'TEXT' to
'EPS '. Word processors are designed to open files of specific types (theirs,
someone elses, or plain TEXT). 'EPS ' isn't a standard for text editors, so
you need to use QUED's option to open anything, or Word similar option (shift-
Open). If you the save this from these applications to a text file, with the
type of 'TEXT' - the default when you do a save as text, this file can be
simply downloaded and printed after a showpage is added (see below).

The PICT preview image is just a binary image in the resource fork of the file.
Depending on how the file was transfered down to the UNIX machine, the 
resource fork may/may not have been sent. My guess is that it was somehow 
appended to the beginning or end of the file.

The correct way to send Illustrator file around the PostScript world :-)
  Adobe Illustrator's native file format is just plain 'TEXT'. Just save your
file as a regular Illustrator file. Then run your word processor and open it
up, if you move the the end of the file you will see some commands that say
something like this:

%%Trailer
Adobe_Illustrator881 /terminate get exec
Adobe_customcolor /terminate get exec
Adobe_cshow /terminate get exec
Adobe_cmykcolor /terminate get exec

  You want to insert a showpage command before the %%Trailer comment - otherwise
the last 4 lines remove the image from the printer's VM. This technique works
for me and has worked for others, should work for you too.
