Very Computer

Hi.

We recently got a new HP 8000 DN printer, and the nice thing is
that it's duplex -- saves trees, less paper to carry around, etc.

The problem is that every once in a while people need to print a
a single-sided job, and it's rather inconvenient to go mess with
the control panel on the printer or fire up jetadmin and turn it
to single-sided mode, then remember to turn it back to duplex after
the job is finished (and before some other job gets sent to the
printer).

Oh, our print server runs on Solaris and we use jetadmin to manage
all our printers.

I've done some digging, and found out that some admins managed to
either use a wrapper to lp/lpr and pass a flag that turns
double-sided printing off for one job at a time, or give the printer
two different names, one for single-sided jobs and the other for
double-sided ones.

Can somebody who has done any of the above please help me out ?

Thanks much,

Gabriel Somlo

The Jetadmin software supports the 'simplex' option to select
single-sided printing:

Original command:  lp -d printer filename

 Simplex command:  lp -d printer -o simplex filename

This should override the default setting for just that one
print job.  A wrapper script around the lp or lpr command
is not necessary.

The lp simplex options seems to be the way to go, but if that doesn't work
for some reason, AND you are printing postscript files, AND your printer
interprets postscript natively, then the following should work.
Prepend the following bit of PS code to your file:

%!
% put printer in non-duplex mode
<</Duplex false>> setpagedevice

lp -o simplex ... works for all my jetadmin-managed duplex printers.

put this at the head of your ps file... anyway, if you have windows system
handy, set different print options in windows and print to file. so you
can find some other useful information.... (you need the right ps draive
in windows of course:)

This will work in _most_ cases. The correct code is _always_ found in
the printer's PPD.
