Improvement are described in the sliding assembly of a plotter and for a method for the adjustment of the spacing between a printing head and the printing media. The improvements consist in that the sliding assembly which comprises the movable carriage and the printing head is mounted on a main sliding guide parallel to the printing media with simultaneous lengthwise sliding capacity on said main sliding guide as well as being pivotable thereabout, until an adjustment value of the spacing between the printing head and the printing media is obtained. An abutment limits the pivot distance of the sliding assembly. The abutment is comprised of a second guide that is parallel to the main sliding guide The sliding assembly comprises two units connected by means of an articulated joint, the mutual position of both units being adjustable as to the angle or rotation.
