How Can I turn off the Startup page on my laserwriter 12/640PS?

[Jerry LeVan]

For some reason my 12/640 insists on printing the startup page
whenever the printer is powered on...

I don't appear to have anyway to turn the rascal back off...

I googled around and found in a postscript faq that something
like:

%!PS-Adobe-2.0
serverdict begin 0
exitserver statusdict begin false setdostartpage end

might do the job.

I sent the above to the printer ( via enscript -Z ).

Lights flashed but powering the print down and up caused
the startup page to be printed...

I don't seem to have any software that lets me control
this aspect of the printer ( trying to start "classic"
from the control panel fails).

Any suggestions?
