Abstract: A system and corresponding method for use when an application prints a document and a corresponding envelope is printed by an independent process, unknown to the application, using soft fonts (dynamic fonts). The system allows creation of a mail piece, which generally consists of document pages and an envelope; the pages to be printed according to data and layout specified in a pages file and using a pages font as indicated in the pages file; and the envelope to be printed with address information extracted from the pages file according to instructions specified in an envelope template file. The instructions of the envelope template file include a layout and a dynamic envelope font, such as a true type font. The system includes a printer driver, responsive to a call to prepare to start printing the pages of the mail piece and in turn for obtaining from the envelope template file the envelope font.

Abstract: The invention is a low-cost stepper motor drive system comprising a microstepping motor and a logic circuit. The logic circuit includes two integrated circuits for controlling one or more phases of the microstepping motor. Each one of the integrated circuits is a motor driver capable of producing up to sixteen microsteps per full step. Further, each one of the integrated circuits takes a set of analog/digital bits and a phase bit as input. Additionally, within the logic circuit, there is included a microcontroller for controlling the microstepping motor. The microcontroller comprises six control bits, which direct the controller in outputting a set of step sequences to the integrated circuits.
