Looking for duplex help with my printer :-(

[Steven W. Orr]

Normally, I don't ever tell people if I know how when they need printer 
help. It just makes them ask you more questions. But then again, maybe, 
I'll get lucky...

I am the proud owner of an HP Laserjet 1320.  I downloaded the specific 
driver for that printer and installed under cups. Now when I run the
lpoptions -l
command, I get the following output:

720 > lpoptions -l

My understanding (and I could be wrong) is that I should be able to say

lp -o Duplex filename

and it should come out double sided.

It does not and I have no idea what to do from here.

BTW, we just installed a Konica-Minolta C353 superprinter and I followed 
the exact same procedure and Duplex (and everything else) seems to work 
just hunky-dory.

If anyone has any suggestions, I'd be grateful.

TIA :-)
