Can't Print After Installing Windows Update 331953

Hi all,

My automatic updater installed the Critical Update 331953
and now I can't print anymore! I am quite certain this
update is responsible since I printed just moments before
installing it. I am printing to an HP LaserJet 4MP that
is connected to a USR8011 11 Mbps Wireless Cable/DSL
Router and other computers using XP on the same network
that have installed the update have the same issue. I
have tried reinstalling the latest printer drivers and
the USR port driver to no avail. Any help is
appreciated.
