I would like to find out whether PCL/5 has some kind of
job termination signal which appears at the end of every
print job, the way that PostScript jobs are terminated with
a control-D.

My LaserJetIII Technical Reference manual mentions something
about a "Job Separation Command" under PCL Command Parsing 
in programming hints... Does anyone know what this is? And
can I count on it being a part of any PCL/5 interpreter?

I know that there is a "Printer Reset Command", ESC-E which
should be the first and last command of every job, but if I
am correct, there is no guarantee that the printer does not
get reset (for whatever reason) in the middle of a job.

Also, does a PCL interpreter send back some kind of signal
along the communication channel from which it received its
input in the way that a PostScript interpreter returns a 
control-D when it has finished interpreting?

Thanks for your help in advance...
