[mod.computers.laser-printers] Apple LaserWriter query

CET1%phoenix.cambridge.ac.uk@UCL-CS.ARPA ("Cambridge Phoenix - CAM.PHX@C (11/15/85)

We have an Apple LaserWriter which is alternately driven over the
RS232 port as an network printer (switch at "9600") and from a
Macintosh workstation (switch at "AppleTalk").
 
Having read Appendix D of the PostScript Language Reference Manual
I thought that one ought to change the "password" required by the
'exitserver' operator from its default of zero. Well, the snag is that
the Mac won't print anything on the LaserWriter if one does this, it
moans about getting PostScript errors.
 
From this I deduce that the Mac must be using 'exitserver' itself, and
needs to know the password. Can anyone tell me how to tell the Mac what
the password it needs is? There doesn't seem to be much in the Apple
documentation that helps here.
 
I suppose this behaviour of the Mac helps to explain why 'vmstatus'
at the start of a job shows about 65000 bytes used just after the LW
has been switched on, but about 108000 bytes after the Mac has been
at it?
