Printing fine lines

[Tosch]

I have to print some rectangular graphics. When drawing lines I can't
seem to make them very fine. Even if I set the pen width to say .1 the
width of the line is the same as if the pen width is 1.

A pixel is the smallest possible element. You cannot draw anything smaller.
You need to decrease the printed size of your pixels, which means increasing
the resolution.
You can compare it to making a mosaic from tiles: to get finer detail you
have to use smaller tiles; covering the same area will mean using more of
those smaller tiles.

Can you give me an example on how to increase the resolution?
Thanks.
