.eps file displays with gv but will not print

[Przemek Klosowski]

It is possible that the postscript file contains something that the
postscript interpreter in the printer chokes on. If you don't have PS
error printing turned on (which is the usual default), the end effect
is that the printer data light blinks briefly and nothing comes
out. Actually that's somethign that you could check easily: send the
print job and see if the printer goes off the READY state and if it
appears to be getting data. If it is, go to the printer front panel
config menus and turn PS printing on, and see if that gives you an
indication of the cause.
