I used  ghostscript -? and got:

GNU Ghostscript 5.10 (1997-11-23)
Copyright (C) 1997 Aladdin Enterprises, Menlo Park, CA.  All rights reserved.
Usage: gs [switches] [file1.ps file2.ps ...]
Most frequently used switches: (you can use # in place of =)
 -dNOPAUSE           no pause after page   | -q       `quiet', fewer messages
 -g<width>x<height>  page size in pixels   | -r<res>  pixels/inch resolution
 -sDEVICE=<devname>  select device         | -dBATCH  exit after last file
 -sOutputFile=<file> select output file: - for stdout, |command for pipe,
                                         embed %d or %ld for page #

After I erased the antialias device, the error was gone. However, although I can
see the page numbers on the left side
and acutally can print out the file, I can't see the context (the gv scree is
blank).  So,  is something  worng with the display?
By the way, I am  talking about  an LM-7.02  on a DELL Latitute laptop.
