I am trying to set up an iPrint printer (HP 4100) so that when I push

down the driver it will be set up for duplex. I used the maptool.htm

to set up the printer and the Driver Settings menu choice to set it up

for duplex. However, when I install the printer with iPrint, it is
not
set up for duplex.

I think the problem is that the printer driver has a 'configure' tab that you need to specify the fact that there is a duplexer installed before you can set the option on the Printer Preferences tab that you

want everything duplexed but there is no option to do that in the
maptool.htm.

How do I get the HP4100 driver pushed down so that it will be set up
to
duplex everything that is printed?
