When we install one of our hp4100 or hp4500 printers though iprint and

configure it with the duplexing unit, envelope feeder and optional
paper
sources. Then we open ie and go to file/print when the print window
opens
we look at any of the tabs in the print window it removes the
duplexing
unit, envelope feeder and optional paper sources check marks in the
print
configuration. We tried other software and it sees to only be ie that

removes the settings.
