Duplex printing

Greetings PostScript gurus.  I am a relative newcomer to PostScript
programming so this question is probably an easy one.

I have an HP IID laser printer with the HP PostScript cartridge (not the
Plus cartridge).  The HP IID has a duplex mode where it will print on
both sides of the page.  The user guide gives some directions for putting
the printer into duplex mode.  Evidently the "statusdict" dictionary
is pushed onto the dictionary stack with the "statusdict begin" command.
Then duplex mode can be set with the "'boolean' setduplexmode" command
where 'boolean' is true or false.

I've been studying "PostScript by Example" by McGilton and Campione, and
it seems to me that a simple

statusdict begin
true setduplexmode

ought to do the trick.  I've moved these statements around, used 0 and 1 for
false and true, put slashed in front of things but so far no joy.  The 
result is always the same; a bunch of light blinking on the printer, a long
delay, and then....  no printout at all.

Any ideas?  Have I included enough info to troubleshoot this or should I 
post more of the PostScript header stuff?  The file I am playing with is
a pretty simple one generated by pstext with a three page printout.

Thanx in advance,  Bob

A couple of days ago I asked about putting an HP LaserJet IID into duplex
mode.

A number of people pointed out that an "end" statement after the above 
commands may help.  Thanks to all who replied.  As it turns out I will
probably never know for sure.  As Leif Arne Neset pointed out, evidently 
both pages of a duplex page must be in memory before the sheet can be 
printed.  Upon closer examination of the HP documentation I found a table
which stated that duplex printing *requires* 4MB of additional add in memory.
Alas, we only have 2 MB in this printer.  Rather than print them out in
in non-duplex, it just pukes on the whole print job.  Lots of pretty blinking
lights but that's about it.

Thanks again to:
