Forgive me if this is covered in the Manual; I bought my cube from Bland and
it did not come with a User manual.  

I use my machine at home and have a NeXT laser printer attached to it. 
However, since I only use the printer once a week or so, I've gotten into
the habit of pulling the plug on it to save kilowatts and wear-&-tear on
the printer.  One day, 'apropos' came up with 'nppower on | off' in
response to something I threw at it.  Wow, I said, just what I was looking
for.  But it doesn't work!  Well, not unless you do an 'su' first.

Here is what I would like to do.  Not being a unix wiz, I'm not sure where
to start.  1) Prevent the bootup sequence from starting up the printer.
              I hope I can just comment something out to get this to work.

           2) Change nppower so that 'me' can power up the printer.

                     or, and this would be much prefered,

           3) Have the printer turned on the first time I try to print
              something.  Of course, this might not work because the
              printer driver may time-out before the laser warms up.

Does anyoune out there have experience with this issue?  I looked around in
/etc/rc, /etc/rc.local, /etc/hostconfig, and /etc/rc.boot, but couldn't 
find anything relevant.  There is a data structure described under the
manual entry for 'np' that stores information on the printer and whether
or not it is turned on.  So if I get real desperate, I will write a
program to do what I want - actually, I'm kind of surprised that NeXT did
not include this functionality in the PrinterManager or Preferences
applications.
                              Thanks,  Peter Marinac
