dead.letter is created when creating a mail (with mail or rmail) is
interrupted. It is created in the current directory which for the spooler
is apparently the qdir directory.

Set up the queue as a PostScript virtual printer with smit mkpq. If you
want to turn off any and all formatting the queue does, do this:

lsvirprt
select queue
_d=p
_j=!
_J=!

With a remote queue to the printer's LPD daemon, you can try to increase the
printer time-out period by appending a -T60 to the backend line in
/etc/qconfig. That may reduce the frequency of this error but I think
you're better off to avoid the lpr/lpd and get the formatting working so
that your PostScript prints when you set up this queue like all the others
and then tweak the virtual printer settings.
