Abstract: Embodiments of the systems and methods provide automated transfer of files between a client computer and a server computer in a networked environment. The file transfer system provides secure data communication using file encryption and decryption techniques. In addition, the file transfer system can automatically translate files to and from various formats as required without user intervention or action. Files can be transferred by drag and drop file operations, scheduled for predetermined times or intervals, or upon the occurrence of user-defined events. In some embodiments, the file transfer system transfers files between a server computer for a bank website and a client computer of a bank customer having an account at the bank.

Abstract: A control system coupled with a laser printer to enhance and expand the capabilities of the printer. A microprocessor with memory components having different functions is coupled between a host computer and the raster image processor of the printer through appropriate interfaces. Bidirectional communication is afforded between the hose and the microprocessor, as well as between the printer and the microprocessor. The system has an audit trail feature which enables the printer to provide security when generating financial forms and negotiable instruments such as checks. The system also has means to facilitate external updating of its control code without changing any hardware on the board.

Abstract: Apparatus for enhancing the permanence of printed images. A substrate with a heated, fused toner image is passed by a PTFE powder coated roller for selective contact therewith by a pivotable engagement bar. The PTFE particles are adhered only to the desired imprinted areas and not to the non-printed and non-selected areas of the substrate. The powder is dispensed on a selective basis to the surface of the substrate. The invention also includes the method for enhancing the permanence of a printed image on the substrate.

Abstract: Magnetic signal level control apparatus for a printer or copier. A continuous sampling of the magnetic characteristics of a reference mark results in constantly adjusting to maintain the specified quality of magnetically readable characters on printed documents. A controller generates a signal which is applied to the developer of the printer to control application of magnetic ink or toner to the photoconductor and consequently to the paper. The invention also includes the method for controlling magnetic signal level.
