manual duplex and n-up printing

I have a HL LJ2300 and am trying to get n-up printing in a duplex
mode. Is this possible and how to set the options. I can get n-up
printing. I can get manual duplexing, but I can't figure out how to
get both at the same time.

Thanks,

Rich

I've used Fine Print with several printers - you can print 2/4/8 on a sheet
of paper and reverse. When you install, it runs a test to see how to print
to get duplex for your printer. I used to use the free version, but
upgraded. Worth every penny. Don't think they have a freebie any more
and the price has gone up, but it looks as if there's a trial period.
