Is it really that simple? I must be missing something because g.Drawline ..... draws a line that is defined by g.penWidth and g.penHeight.

Right.

 Since the smallest setting is 1 (pixel), the line drawn is not a hairline.

Sure it is, if your pixels are a hair's width.

The printer is set at 600 dpi.

If it's properly set to that, then a 1-pixel line is 1/600th of an inch thick. That's going to be too small to easily see; you'd probably want to set the pen size to 2 or more even for a hairline, at that resolution.

But I suspect that your printer resolution isn't really 600, and that's why you're not getting hair-thin lines.

Best,
