All of our HP LaserJet's (with LCDs, anyways) support it, and even
some of the Business Inkjets support it.  None of the DesignJets
support it, however...

I have considered changing to using RDYMSG and then adding another
RDYMSG for the end-of-job code, however that could still leave the
last message displayed if there is a problem with the job...

This should only be an issue with LaserJet 4 and earlier printers;
I believe that HP added the JOB DISPLAY stuff for the LaserJet 5
series printers.
