Abstract

This invention will allow standard wire (dot matrix, graphics, etc.) printers to be able to print perforations in the paper. This requires modification to the printer, but allows the printer to print standard or custom perforations under program control. This would allow customizing forms or labels on the fly under program control. Any cutout shape could now be printed.

Programmable Printer Perforation

      This invention will allow standard wire (dot matrix,
graphics, etc.)  printers to be able to print perforations in the
paper.  This requires modification to the printer, but allows the
printer to print standard or custom perforations under program
control.  This would allow customizing forms or labels on the fly
under program control.  Any cutout shape could now be printed.

      An additional printhead element that is designed to cut through
paper can be added.  This could be added to the current printhead on
the existing printers.  Software needs to be changed to address this
additional head.  With this, a program can be set up to cut the paper
with a series of strikes that would end up being equivalent to a
laser perforation.  This cut could be horizontal, vertical, diagonal,
circular, or any other graphic shape that can be programmed.  The
platen can be modified with a groove to allow the printhead to pass
through the paper, to cut the paper.

      This has been tested on the standard printhead of an IBM 5182
color printer, without a modified platen.  To retrofit an existing
color printer, it is necessary only to use a black and white only
ribbon, and score the paper by printing in the color portion (which
is now absent from the ribbon). This allows the standard printhead to
hammer through the paper into the platen.  The platen could be
modified in this area (with a groove cutout) to facilitate cutting.
