Yes, without it the printer will only feed single pages and
print single-sided. In the printer menu (here: Laserjet 4000
operator panel), duplex capability needs to be selected "ON",
because this seems to override the "duplex request" from the
computer. Maybe you can check duplex in the web configuration
interface of the printer?
If I remember correctly, -dDuplex=true will generate the
correct portions of PCL to have the printer use the duplexer.
It's hard to check what "commands" actually arrive in the PCL
sent to the printer. :-(

So it seems to be configured in the correct way already...
