Linn Boyd Benton invented a pantographic engraving machine for type design, which was capable not only of scaling a single font design pattern to a variety of sizes, but could also condense, extend, and slant the design ( mathematically, these are cases of affine transformation, which is the fundamental geometric operation of most systems of digital typography today, including PostScript ).

In another application similar to drafting, the pantograph is incorporated into a pantograph engraving machine with a revolving cutter instead of a pen, and a tray at the pointer end to fix precut lettered plates ( referred to as'copy'), which the pointer follows and thus the cutter, via the pantograph, reproduces the'copy'at a ratio to which the pantograph arms have been set.
