Abstract: A computer system includes an application with the ability to select printer settings from any of a variety of potential sources, and associate the printer settings with a document to be printed. The potential sources may include user-selected sets of printer settings that are particular to the document to be printed, are associated generally with the documents to be printed using the application, and globally associated with the computer system. The potential sources may also include a set of content-provider printer settings associated with the document and selected by a content-provider of the document.

Abstract: A blank determining section performs scanning of a text part of e-mail when receiving e-mail. The scanning of text part is carried out up to a next boundary. After the end of scanning, the blank determining section determines whether or not there is any code other than unprintable codes such as a blank, a tab, a line feed, and the like. Since the text part is composed of only a line feed, the blank determining section clears data of the text part from a mail reception memory area. An image part is normally printed. As a result, the printing of text part is skipped, and only the image part is printed. This makes it possible to prevent a useless output and an output of inconvenient information.

Abstract: A color printing system and method for reducing bidirectional hue shift in inkjet printing. A set of data channels for the ink colors of the system is generated, including at least one print-direction-independent data channel, and at least one pair of print-direction-dependent data channels. A print controller receives the set of data channels for printing, and selects the print-direction-independent data channels, and one of each pair of print-direction-dependent data channels, to provide the data for printing in each opposite scanning direction of the print engine.

Abstract: The toner in the toner cartridge is determined by taking each of the rasterized images output by the RIP and evaluating the pixel levels over the surface thereof. The average value is determined as a percentage of the maximum toner that can be applied to the page. This is then subtracted from a toner value and a remaining toner level determined. Further, all pages of the rasterized document can be evaluated to predetermine the toner level after printing. If this falls below a predetermined minimum, printing is inhibited for that document.

Abstract: A method for securely controlling the printing of a plaintext document generated by a first source includes the steps of receiving at a printer via a first communication channel a first key sent by the first source and obtaining at the printer a second key based on communication between the printer and a second source. The printer receives from the second source via a second communication channel an encrypted version of the plaintext document. The printer decrypts, using the first and second keys, the encrypted version of the plaintext document to obtain the plaintext document at the printer and then prints the plaintext document. A system incorporates the method.

Abstract: Using a picture image printing system, both types of pictures recorded by a camera using a film and a digital camera are effectively printed. The printing system comprises a film scanner for inputting a picture recorded on a film, and a card reader for inputting a picture recorded by a digital camera. By switching these upon necessity, digital image data are obtained. An image processing apparatus carries out a pixel number conversion on the digital image data keeping an aspect ratio of the image constant so that the picture image data are printed in a width almost the same as a width of rolled paper. The digital image data whose pixel number has been converted are printed in the form of a print on the rolled paper by a printer.

Abstract: An electrostatographic recording method for printing an image on a receiver comprising the steps of: operating a primary charger to establish a uniform primary voltage level on an image recording member; developing a control patch on the image recording member, measuring density of the control patch to thereby provide a density measurement signal; converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information; rendering the digital bitmap by defining each pixel as either a background pixel, interior pixel, or an edge pixel and reassigning the digital value of one or more of edge pixels or interior pixels independently and as a function of the density measurement signal; modulating electrostatic charge on the image recording member as a function of the digital bitmap after rendering.

Abstract: In a printing system, a developed photo filmstrip is put in a film scanner to pick up image data from all picture frames photographed on the filmstrip. An index image of the picture frames is displayed based on the image data, so a user selects picture frames to print with reference to the index image while designating a print size to each picture frame. The image data of each designated picture frame is compressed at a rate that is decided according to the print size. The higher compression rate is used for the smaller the print size. The compressed image data and print order data are transferred to a work station of a photofinisher. The photofinisher reproduces the original image data from the compressed image data, and makes prints based on the image data and print order data.

Abstract: For obtaining a print result of the image quality in which the color reproducibility is always stable even if receiving a printing job from any client computer, a first calibration control unit obtains correction data from a printer to store the data in a first memory, receives normal print information from a client computer, and corrects print data by referring to a correction table produced in accordance with the correction data when generating the print data based on the received print information.

Abstract: When highly redundant information that expresses five tones using 4 bits is transferred to a printer in terms of a unit data length in data transfer, efficiency is very poor. Hence, multi-valued data is quantized to 5-valued data, which is output as a 4-bit code that can express five values. 4-bit codes for three bits are combined to be converted into an 8-bit code. The 8-bit codes are packed into data of a 16-bit unit, and the packed data is transferred to the printer.

Abstract: Remote data entry is performed in such a manner that a plurality of entry items and a plurality of data items are caused to collectively enter within one communication and the check sum is calculated simultaneously with the data entry so that abnormality of the data is easily detected even if the contents of the entry data are changed due to the abnormality occurring in a facsimile apparatus. Data is collectively stored in a receiving buffer and a great quantity of data is caused to remote enter if the capacity of the buffer permits. After all remote data entries have been completed, the check sums of all entry memory regions are performed so that the memory capacity of the program code of the check sum is saved.

Abstract: The present invention has an object to avoid an inconvenience of potentially not being able to use a department managing function.
