These margins are always used for printing, whether the drawing destination is a post-script-dc% or printer-dc%. The margins are in the units of the destination printer-dc% or post-script-dc%. In the case of post-script-dc% printing, the editor margin is in addition to the PostScript margin that is determined by set-margin.
