Parallel port bits are latched until you write something else to the port.
At least that's how it worked with 8088's and 286's when I was doing this
back in the 80's.

Something I just thought of.  You can get an HP Jetdirect print server with
one, two, or three parallel ports.  Hooked to a wireless AP, it might solve
your problem.

Another thought, 2.3 gigahertz 802.11b bridges may give inconsistent
connections in a mobile environment.  Every time the orientation of an
antenna changes, the link will have to reprogram itself to adapt to the new
geometry.  Results with a 2.3 gig camera system I had was inconsistent.
Give it a try though, the wireless network stuff is cheap enough nowadays.
