Does your printer have CE versions of the fonts you are using (here
Helevetica, I think)? This will only work if it does, and that's
not an R issue. Printers with Adobe engines sold in the UK do not.
You may well need to switch to, say, the URW clone of Helvetica
(as gv works, that probably does have the characters) *and* use the
appropriate afms. You will need to arrange to download them too.
n019003l.afm seems to contain the chars.

Char 127 is not defined, 160 is a non-breaking space but I suspect you
mean some later ones.
They will not be centred if they are not in the afms: and then they
are probably not in the Adobe fonts.

They may well be downloading fonts.
