Please don't get me started on the wretched horror that is the Windows printing sub-system. Other than inexplicably missing half of the important information therefore either relying on guesses or custom drivers, the units in use are not consistent requiring a library of conversions between one API call and the next. Not helped as the American's who came up with it are under the deluded impression that the entire world uses American paper sizes and measurements and therefore the accuracy is based on these units of measure, nothing more accurate. You can still this now if you set a margin to a nice round value in metric, Windows will re-round it to the nearest imperial measurement and convert it back.
Biting the hand that feeds IT
