Java Printing Graphics Uniformity

Java Printing Graphics Uniformity

I am printing a number of rectangle that I draw on screen. The rectangles
overlap so that it looks like a grid of rows and columns. Everything
appears as expected on screen.
I've tried various ways to print (implementing printable), but I can't get
the same quality.
Using JComponents print method is grainy (even with buffering off).
Redrawing directly to the print method Graphics object causes darker lines
where rectangles overlap, and lighter lines where they do not (regardless
of the alpha composite). I've tried various RenderingHints with this
method.
Printing a constructed buffered image directly to the printing graphics
gives consistent quality, but certain lines appear thicker than others so
that an entire column or row would have one thick border along one side.
Does anyone know why this might happen?
