Abstract:
An additional control device or a cartridge mounted on an electronic equipment such as a laser printer, and a device and method for processing information by means of the cartridge (503), which facilitates the improvement, addition and alteration of electronic equipment that have been conventionally impossible. A cartridge (503) mounted on a laser printer (500) is provided with a RISC type processor (601) and a data transfer control part (603) of an ASIC, etc. The microprocessor (601) receives the data to be printed via a read-out control circuit (620) or a FIFO control circuit (623) provided in the data transfer control part (603). Then, it expands the data into image data and stores them in RAMs (611-614). Thereafter, it transfers the image data to the side of an electronic control equipment via double bank control circuit (624). The read out control circuit (620) and the double bank control circuit (624) transfer the image data to the side of the microprocessor (601), using a data bus which is a read only data bus when viewed from the electronic control equipment. The image data are printed by a laser engine (505).
Abstract:
On a printed board (550) of a cartridge (503) are arranged a microprocessor (601), a ROM storing a processing program for the microprocessor (601), and a ROM storing a processing program for a processor in a printer body. When the cartridge (503) is inserted in the printer body, the processor in the printer body reads discrimination data stored in the ROM in the cartridge, and the processor in the printer body performs the processing according to the predetermined processing program in response to the discrimination data. The microprocessor (601) is arranged at the rear end of the cartridge when inserted so that it can effectively dissipate heat outside.
Abstract:
Data are transferred from an electronic equipment to an additional control device without any signal line for transferring the data. An electronic equipment to which data are transferred, e.g., an electronic control equipment in a printer outputs the data to be transferred by reflecting the data in the lower order eight bits of an address signal line (CAB). By this assignment of an address, the data corresponding to the address is read out from a ROM (671), and is latched by latches (651, 652), and further, the additional control device is informed of the latching of the data by a signal EWRDY. When a microprocessor of the additional control device, i.e., a cartridge reads the data latched in the latches (651, 652) via a data bus (DB29), the data transfer from the electronic equipment is completed. Even in the case of the absence of the data bus or in the case of a read only line, the data can be transferred to the additional control device, and be processed on the side thereof.
Abstract:
The present invention concerns a transaction printer for generating and cutting a receipt which printer uses the capabilities provided by configuring linked command sequences to provides for logo headers, logo trailers, watermarks, and margin message logos as configuration options. Additionally, the ability to map existing text attributes to new sets of attributes that may include color is also provided.
Abstract:
In case of processing information by mounting an additional control device on an electronic equipment, data are transferred at a high efficiency between the electronic equipment and the additional control device. The electronic equipment to which data are transferred, e.g., an electronic control equipment in a printer outputs the data to be transferred by reflecting the lower order eight bits of an address signal line (CAB). By this assignment of an address, the data corresponding to the address is read out from a ROM (671), and is latched by latches (651, 652), and further, the additional control device is informed of the latching of the data by an interruption request signal AMDINTO or a signal EWRDY. When a microprocessor of the additional control device, i.e., a cartridge reads the data latched in the latches (651, 652) via a data bus (DB29), the data transfer from the electronic equipment is completed.
