摘要： A page printer with an internal CPU, interrupt controller, and DMAC has a DMA stopping circuit in the DMAC, the function of which is to stop a DMA transfer in response to a DMA stop signal and restart it in response to a DMA restart signal. The DMA signal is generated by the interrupt controller when it receives certain interrupt requests, such as communication interrupt requests, enabling the CPU to service these requests promptly. The DMA restart signal is generated at the end of the interrupt service routine. This arrangement permits DMA transfers to be performed in burst mode, stopping only when urgent interrupt service is required. Burst-mode DMA improves the speed of operation of the printer.

摘要： An image data conversion method for converting the image data signal to the runlength signal through the process for reading once or several times a runlength code from a runlength conversion table for a given image data signal and a process for adding the pertinent runlength code when the same type of runlength code appears continuously. A character code/character pattern conversion apparatus which uses said image data conversion method, and provides, moreover, a multiplication device for multiplying character enlarging coefficient and the runlength code and a character interval inserting means which adds a character interval width code to the enlarged runlength code and outputs the input character code after converting it to the enlarged character pattern along with the interval code.

摘要： In a technique for storing data representative of characters and symbols of a font in a compacted manner, interstitial bank spaces between characters are removed. The proper symbol is addressed during decompression by combining a calculated approximate pointer with a limited range correction factor stored with the font to obtain an exact start of symbol pointer utilized to address the image data for the symbol. Also stored with the correction factor is data indicating the vertical positioning of the symbol within the character box.

摘要： A circuit arrangement for storing a text of characters and of combination characters composed of a plurality of characters has the characters assigned code words which can be input into a working memory. The working memory contains a text memory in which the code words of the characters, and possibly the code words of a character of the combination of characters of a given portion of a text, can be stored in the form of primary groups and in which, where applicable, the other characters of the combination characters can be stored by hierarchically classified subsidiary groups. The working memory contains an assignment memory for storing items of assignment data which are associated with the primary groups and the subsidiary groups and which indicate the position and number of the character positions of each primary group and of the subsidiary groups.

摘要： A font substitution printer serving as a character output device includes a substitute font generation section, a storage section and other sections. The storage section includes a font attribute data base consisting of the font names, typeface names, encoding names and metrics names of loaded fonts and usable fonts, a typeface attribute base, and a substitute encoding data base storing therein information as to a relationship between encodings and other encodings which substitute for the former encodings. The substitute font generation section extracts a typeface name, an encoding name and a metrics name from an output requested font name, selects a substitute typeface most similar in the typeface attribute to the extracted typeface name, and, out of substitute fonts consisting of one or more loaded fonts which satisfy not only the substitute encoding that is obtained in accordance with the extracted encoding name but also the selected substitute typeface, creates a substitute font with the weight or metrics thereof adjusted.

摘要： A character output device comprises a storage section for storing typeface property data consisting of quantitative and qualitative information of the specific parts of specific characters that are commonly possessed by a plural number of fonts, a distance calculating section for calculating a distance between typeface property of a font the use of which is requested and any of other fonts than the use requested font, and a font selector section for selecting, on the basis of the calculation result, a font of which the typeface property is closest to the typeface property of the use requested font. In the character output device, when a font with the same typeface as that of the use requested font is not retained in the character output device, a control section and a character development processor section cooperatively substitute the typeface of the retained font selected by the font selector section for the typeface of the use requested font to perform a character processing. An output section outputs the result of the character processing.

摘要： A printer that allows a plurality of personalities access to a common rasterizer. The printer is constructed of an operating system, a scaleable font and a personality interface. The scaleable font is logically connected to the operating system as is the personality interface. Additionally, the personality interface is logically connected to the plurality of personalities and the common rasterizer. The personality interface allows the plurality of personalities to communicate with the operating system and the common rasterizer. When the operating system receives a print job, it activates one of the plurality of personalities to become an active personality. Next, the operating system sends the print job through the personality interface to the active personality and gives the active personality exclusive access to the common rasterizer.
