Our LaserWriter is hooked to a MicroVAX II running 4.3 BSD. We use it
with TeX (dvi2ps) and ditroff (tpscript). The printcap entry is as
follows:

lw|Apple LaserWriter:\
	:br#9600:fc#021370:fs#000000:lp=/dev/ttyS0:sd=/usr/spool/lpd/lw:sf:sh:

To catch the LaserWriter's diagnostics that are issued while it is processing
a job, you can use the following tricks:

a) tip to the LW _before_ sending the printjob via lpr or 
b) (better!) insert the following lines in your /etc/rc.local:
  
   /usr/ucb/tail +0cf /dev/ttyS0 > /usr/spool/lpd/lw/lw-log &
   echo 'loggin LaserWriter's diagnostics on /usr/spool/lpd/lw/lw-log'\
   >/dev/console
 
With 'tail -f <logfile>', everybody will be able to monitor the LaserWriter's
diagnostics. We found this very helpful in debugging PostScript applications.
