I remember this.  In my last job I found the points printed on a local
printer but not on the networked printer.  I suspect this is because 
the PostScript rendering was done by different RIP software.  It was a
nuisance for me because the nicer printer would not print the points.

I remember trying Allan Hayes' solution of...

I remember it worked provided you had big chunky dots, but when the dots 
got beneath a certain size they disappeared.  This is remembering back a
couple of years, so don't take my word for it.  But try another printer 
if you've got one around (what me, an engineer? some mistake, surely?).

Cheers.
