I attemped to reproduce this and was unable to.  When I scanned an HP
LaserJet 4050N with JetDirect firmware revision G.08.03, one of the
ones listed as being vulnerable, the printer did not lock up in any
way.

The nmap command line used was:

 nmap -sT -PT printername

attempting to exactly duplicate the one in the original report.  This
was tested with nmap versions 2.3BETA14, 2.12, and 2.30BETA20.

Any further details from people who have successfully produced the
problem might therefore be useful.
