// resolution which is 72 dpi (probably inspired by Postscript).
// 2 - To have a sufficient resolution, this is increased by 16 times,
// by using the scale method of the graphic object associated to the
// printer. This gives a 72 dpi * 16=1152 dpi resolution.

// resolution. Calculating 1152 dpi / 200 dpi gives the 5.76 constant
