摘要:
A data processor and a host device are bi-directionally communicably connected to each other. The data processor includes a process-executing unit and a progress-status-saving unit. The process-executing unit executes a prescribed process when a process-requested file is written in a prescribed folder. The progress-status-saving unit saves progress status data indicating a progress status of the prescribed process so that the progress status data is retrievable by the host device.

The invention discloses an image processing apparatus for adjusting the saturation of an input image. The input image also has a lightness and a hue. The image processing apparatus includes a look-up table, a processing unit, and a multiplier. The look-up table is used for recording M lightness ranges, N hue ranges, and M*N corresponding gains. The processing unit is used for storing the look-up table and, according to the look-up table, for judging that the lightness of the input image is located in which lightness range, and the hue is located in which hue range, so as to determine a corresponding gain from the gains. The multiplier is coupled to the processing unit and used for multiplying the saturation of the input image by the corresponding gain. Accordingly, the image quality is improved.

With the present invention, an interrupt print job processed according to an interrupt print instruction can be prohibited from being interrupted by another print job in multiple. With the present invention, if an interrupt-instructed print job has not been processed actually, the user of that print job can be notified of it.

Provided is a method, system, and program for interfacing with a printer driver. Data and an acknowledgment request is received from the printer driver. The printer driver does not send further data to print until receiving an acknowledgment reply indicating that the transmitted data passed an initial check to improve printer performance. An acknowledgment reply is transmitted to the printer driver in response to the acknowledgment request before completing the initial check of the sent data to cause the printer driver to send further data. Data processing operations are resynchronized in response to detecting an error in the received data. The received data is rasterized and outputted.

An image forming apparatus is disclosed which includes a power-on section which supplies power, a storage section which stores image data, a printing section which prints image data stored in the storage section, an instruction section which accept an instruction to print using the printing section, a processing section which initializes the storage section upon turn-on of the power-on section, a time measurement section which measures time required at least for the processing section to execute processing, a report section which reports that the apparatus is in a state in which the instruction section can accept the instruction to execute printing, a control section which controls, upon turn-on of the power-on section, report of the state in which the instruction section can accept the instruction to execute printing before completion of initialization of the storage section.
摘要:
A host sends each page of image data to a page printer in band units and the page printer writes the received each band data into a reception buffer in DRAM by DMA and transfers the band data from the reception buffer to an image formation section made up of members. The host gets an available buffer capacity from the printer just before transmitting each band data, and transmits the band data only when the printer can receive the band data. In the printer, a CPU permits transfer DMA to be started after reception data as much as the data amount calculated based on the data reception speed and the transfer rate is stored in the buffer to prevent an underrun error from occurring. If an underrun error occurs, the CPU sets an error flag, and sends the error flag to the host just before the host starts transmitting each band data. When receiving the error flag, the host drops image resolution and resends the page data with the resolution dropped.

A high-efficiency printing apparatus, a printing system, a print control method, and a storage medium require an extremely small-capacity receiving buffer memory of a printing apparatus and put an extremely small burden on a host apparatus. A PC has an IEEE 1394 interface section for communicating with a printer, a memory that can be accessed by a printer and that stores text data, and a CPU that provides the printer with an information block that includes address information of text data. The printer has an IEEE 1394 interface section for communicating with the PC, a printing section for printing on a recording medium, and a CPU that reads text data stored in the memory of the PC on the basis of an address of the information block that includes the address information of the text data provided by the PC, and causes the printing section to perform printing.
摘要:
A method and an apparatus used, for example, in conjunction with a computer or similar device, provides for multi-resolution rendering of image data, where the image data includes background image data, vector data and text data, so as to accommodate memory capacities of rendering devices. The computer may send image data in a multi-resolution format from the computer to one of several rendering devices. The multi-resolution format may be achieved by frequency domain coding or generation of image swaths, or a combination thereof. The image data may first be sent in a low resolution format, and a rendering device determines, based on its memory, whether the corresponding image or text should be rendered. Next, vector data and/or text data may be supplied to the rendering device. Then, higher resolution data may be sent after the text/vector date so as to maximize memory usage of the rendering device. Additionally, in a printing application, the image data may be divided into swaths, with each swath separately provided to a printer.

During print processing based on print data from host computer 100, if memory shortage occurs in RAM 16, information on the occurrence of memory shortage, memory-use status and the like is sent to the host computer 100. The host computer 100 receives the information and allocates a storage area in the RAM 3 based on the information. Form information and the like, registered in the RAM 16 are transferred to the host computer and saved in the allocated storage area, thus expanding an available area of the RAM 16 for printing. When the print processing has been completed, the completion of printing is notified to the host computer 100, so that the saved information is transferred from the host computer 100, and stored into the RAM 16.
