Ahh yes, I see it now :-) Tried it on an old Laserjet 4000 and it works 
perfectly.
The first printers I tested it with was a Laserjet 4350 and a 
ColorLaserjet 5550. Here the info is on the display for a second or 2 
(depending on the size of the job) and the rest of the time the display 
prints "PROCESSING JOB FROM TRAY 3" or something similar. 

I still wonder why most of the PPD's for the HP printers has an empty 
JCLBegin string?

For some uses it would be nice to have a message stating "Job finished 
for user blabla" or something like that staying on the display after 
the job is finished.
