I'd reckon you need to write your own printer firmware, or built your 
own controller hardware. I'd imagine there would be a lot of printer 
settings you cannot set through the PC connection. They are not a "dumb" 
printers.

If the ink drop can be placed with very little randomness, and is 
repeatable, then software can in theory compensate for any 
misalignments.  If the drops are too random then it will be a 
mechanical problem that software cannot fix.
I think if the head were to travel much slower then the randomness will 
be reduced.
