Michael, in a non LSPP system environment your summary is correct.

In an LSPP system, since the label is bound to the document (file)  
with some assurance, you can print real labels on documents. We spool  
multilevel print jobs from our Compartmented Mode Workstations (B1  
era MLS) with print banners that reflect the document classification  
- not the network system high. Banner pages and markings at the top  
and bottom of each page. Accredited in 5 different countries and  
multiple domains :)

DoD is not the only set of US rules (DCID 6/3 vs DoD 8500) and other  
nations have their own rules. If possible, I would certainly like to  
see real multilevel printer support. Anything less will be a step  
backwards for our users.
