摘要： A method for controlling a printer having a plurality of print engines and a print engine controller includes the steps of: (a) coupling each of the print engines to a corresponding print engine communication device; (b) coupling together the print engine communication devices and the print engine controller in a daisy chain configuration with a serial data link, the data-output port of the printer controller being directly coupled by the serial data link to a first one of the print engine communication devices and the data-input port of the printer controller being directly coupled by the serial data link to a last one of the print engine communication devices; (c) embedding commands and data in a data stream by the printer controller and transmitting the data stream on the serial data link to the first print engine communication device by the printer controller; (d) relaying the data stream from the first print engine communication device back to the serial data link by the first print engine controller; (e) receiving the data stream from the serial data link by the last print engine communication device; (f) relaying the data stream from the last print engine communication device back to the serial data link by the last print engine controller; and (g) receiving the data stream back from the serial data link by the printer controller. Preferably, one of the first and last print engine communication devices performs the steps of extracting a command from the data stream and executing the command; and in the course of executing the command, it performs the steps of extracting bitmap data from the data stream and placing the bitmap data in a memory storage buffer coupled to a video data input port on the corresponding print engine. The method may also include the step of transmitting a message from the one print engine communication device to the print engine controller over the data link, where the message indicates that its memory storage buffer is ready to receive additional bitmap data, thereby allowing the print engine controller to be able to perform on-demand dispatching of the bitmap data to the print engines.

摘要： An electronic image registration system for a high-speed raster printer controller includes dedicated hardware for performing run-time registration, in both the horizontal and vertical directions, on a continuous stream of rasterized bit-map data generated by the rendering units of the raster printer controller. The registration takes place in hardware, between the rendering section of the controller and the print engine, thus allowing the registration to be performed in real-time without slowing the controller's processing speeds. The dedicated run-time electronic-image registration hardware for the vertical registration of the image includes a vertical holding register and a vertical counter. The vertical holding register is loaded by a CPU and indicates the magnitude of the vertical registration, which in turn indicates a length of delay in scan-line units before the start of the page-map's print cycle after seeing a “top-of-form” signal from the print engine. The dedicated run-time electronic-image registration hardware for the horizontal registration of the image includes a barrel-shifter, a data bus coupled to the input port of the barrel-shifter for transmitting the data stream to the barrel-shifter one block of scan-line data at a time, a history register coupled to the output of the barrel-shifter, and a logical adding device having a first addend input port coupled to the output port of the barrel-shifter and a second addend input port coupled to the output port of the history register.

摘要： An on-board diagnostic system which comprises dedicated hardware for performing run-time diagnostics on a computer board having several functional sections. The diagnostic system utilizes a serial token ring network, which preferably has a software-independent, hardware core, comprising a non-intelligent master device and a plurality of non-intelligent slave devices. The master and slave devices are all interconnected via a dedicated serial data bus which operates independently of the on-board CPUs and on-board CPU buses. Each slave device is responsible for monitoring a particular section of the computer board. The master device polls each slave device by activating a corresponding token line on each slave device for a predetermined period of time, one at a time, until the master device is alerted by a slave device that a change of state has occurred in the status signals of that particular section. If there is a change in state for that particular section of the board, the corresponding slave device will begin transmitting data on the serial bus the next time that the Master device activates the token line for that slave device. Once the master device sees this activity on the serial bus, the master device will then maintain the corresponding token line active for a predetermined period of time in order to receive a bit-stream from the corresponding slave device over the serial data bus. Preferably, the bit-stream contains a source address (the address of the slave device sending the message), a destination address (the address or addresses to which the message data is to be sent) and the data which indicates the change. The master device will then transmit the diagnostic data to the particular destination devices indicated by the destination addresses.

摘要： A method and architecture is provided for merging a variable image data bitmap into a template image and for transmitting the merged image to a print engine; where the template image is defined by rendering commands derived from a page description language, and the variable image data bitmap is taken from a list of the variable data bitmaps. The method comprises the steps of continuously rendering template image data bands, in accordance with the set of rendering commands, and transferring the template image data bands to a mass storage. Once the entire template image is stored in the mass storage, the variable image data bitmap is merged with the template image bitmap and sent to the print engine by continuously loading template image data bands from the mass storage, logically mapping the variable image data bitmap into the template image data bands to produce merged image data bands, and dispatching the merged image data bands to the print engine. Preferably the loading, mapping and dispatching steps are performed for each variable image bitmap in the list to thus print a corresponding plurality of the templates having respective variable data printed therewith.

Accordingly, all of the piezoelectric crystal clock sources will also be synchronized in phase as well as frequency to each other.

摘要： A digital high-speed printing system architecture for processing contiguous raster-image data blocks for transmission to a marking engine, comprises a central processing unit ("CPU") and at least one video RAM device. Each video RAM device includes a dynamic band RAM, a serial access memory, a random access port for transmitting and receiving image data blocks to and from the dynamic band RAM, and a serial port for transmitting and receiving image data blocks to and from the serial access memory. The video RAM devices perform bi-directional image data block transfers between the dynamic band RAM and the serial access memory. Furthermore, the video RAM devices transfer image data blocks to and from the serial access port, and simultaneously transfer of image data blocks to and from the random access port. A CPU data bus is coupled between the CPU and the random access port for providing CPU access to the dynamic band RAM, such that the CPU can perform mapping operations on the image data blocks in dynamic band RAM. A dispatch FIFO is coupled to the marking engine; and serial bus is connected between the dispatch FIFO and the serial port, such that image data blocks can be dispatched from the serial access memory to the marking engines over the serial bus. Therefore, the system architecture allows for the dispatching of image data blocks from the serial access memory to be performed simultaneously to the mapping of image data blocks in dynamic band RAM.

摘要： An electronic image registration method for use with a high-speed raster printer controller provides run-time registration of an image which is defined by a continuous stream of rasterized bit-map data. The method includes the steps of: (a) detecting a misalignment of the image with respect to a form, and producing a registration value in response to the detected misalignment; (b) acquiring a present block of the bit-map data from the stream; (c) shifting the present block of the bit-map data a number of bits according to a shift count generated from the registration value produced in step (a) to create a present contiguous set of shifted bit-map data bits and a present contiguous set of spill-over bit-map data bits; (d) storing the present set of spill-over bits; (e) combining the present set of shifted bits with a previous contiguous set of spill-over bit-map data bits to create a present registered block of bit-map data; and (e) dispatching the present registered block to a print engine. The method preferably operates in hardware positioned between the rendering section of the raster printer controller and the print engine, thus allowing the registration to be performed in real-time without slowing the raster printer controller's processing speeds.
