gv, gs problem?

[gqin fit edu]

I have some problem with gv or gs in my core 1. If I print a page in
mozilla, only the title line is printed, but if I print it into a ps file
and try to open it with gv, or ggv, an error message of "invalid ps
format" would appear. Also I can get the same error to open a ps file
generated in other machine with Redhat 9 by "mozilla -- print to file".
But in the core 1 I can open and print the ps file generated by "latex +
dvips". My system: gv-3.5.8-23, ghostscript-7.07-11, mozilla-1.4.1-18.
Thank you very much!
