I ran at 2 different sites into problems with NDPS after the Update to
At the first site, a printer with builtin network card did not
receive/serve any printjobs anymore. Using the same driver printing
direct from the xp workstation to the networked printer did work.
All Printjobs via iPrint/NDPS were served, but scrambled or deleted.

As soon I attached an external printserver and connected the printer to
the printserver, it worked on an instant. One could think, the builtin
PS is just not working, but it did with SP2, SP3, and SP4 .
