how to get mouse resolution?

Hi,
Usually mouse resolution is higher than screen resolution. How to get
mouse resolution from Java? How to move mouse to a different screen
location using mouse resolution?
Also it seems, mouseMove event is generated only when mouse moves on
screen (may be a few pixels). How to get a mouseMove when mouse is
moved, but pointer in screen is not mived (as screen resolution is less
than mouse resolution, mostly 72dpi)?
I am trying to have a scribble application, where user draws
something with mouse in the panel. But, as mouseMove is mapping mouse
into screen coordinate (may be a with a few pixel quantization also) I
am loosing some minute detail in the coordinate value, which might be
present in the drawing. Later I want to get the exact image at the
subpixel level without loosing detail, while zooming.
So basically, I want to capture mouse movement, and mouse position wrt
some reference at mouse resolution, rather than screen resolution.
Any possible solution (including native) ?

Any help is appreciated.
