The invention comprises a mechanical handwriting system linked to a user input system to generate a plotted document, such as a greeting card, note card or document, using a conveyor belt unit to support and move the document, a plotter, and a series of rollers to position and constrain movement of the greeting card, which is optionally and preferably linked to a paper feeder system in an assembly line format, where the rollers are optionally and preferably adjustable in position to accommodate varying paper sizes and to allow movement of the document during a plotting period to avoid positional overlap constraints of the rollers and a plotter head of the plotter in a process of plotting the document/card in sections.
