I've been experimenting with the lp command on my hpux box, but can't figure how to specify that the paper should be pulled from tray 1. Also, out of curiosity, is it correct in saying that the lp command ignores options it doesn't have? for instance I tried this
lp -d printer1 -olandscape -olpi8
and the output was landscape with a smaller gap between the lines, so i tried
lp -d printer1 -olandscape -olpi10
and it was just landscape, but when i tried
lp -d printer1 -olandscape -olpi12
and the lines were so close together, they appeared to overlap. So apparently there isn't a landscape with 10 line per inch option it would seem.
