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
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

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