This already IS the biggest problem with a inkjet/bubblejet.  That is why
they are now using a rubber-gasket that they hide the head in when not in
use.  Some models actually squirt some ink into it each time they land...
To keep it moist.  Then they seal off.  Each time you turn the printer on,
it goes through a head cleanup to remove any leftovers from sitting in the
gasket.
