Abstract: A printing system and method is disclosed herein which is capable of emulating any of a plurality of phototypesetters to create a proof comprising at least one glyph on a reproduction medium from composition data. The proof is created from page and font data encoded in any of a plurality of formats, such data including an identification of the particular format in which the data is encoded. The system processes the font data and page data a first time in accordance with the identification to derive an encoded representation of the glyph to be reproduced. The system processes the page data a second time in accordance with the identification to derive character and typesetting commands which together define the placement of the glyph on the reproduction medium. An output device is controlled by the system in accordance with the encoded glyph representation and the character and typesetting commands to create the proof on the reproduction medium. The system is capable of emulating any one of a plurality of phototypesetters and can reproduce proofs on inexpensive medium, such as plain paper.

Abstract: A plurality of language display control cards are provided for insertion into the motherboard of a personal computer, each card having connector means to which a CRT display and a keyboard may be connected. Each card controls its display independently of the others so that different data may be displayed on each display screen. A display control card includes a font memory for storing the digital video representations of ideographic characters of a standard code, and an ASCII memory for storing the digital video representations of ASCII characters. In addition a loadable font memory is provided for storing the digital video representations of characters which are not commonly used characters of a language but may be frequently used in a particular application. The outputs of the three memories may be serially interspersed so that the CRT may display ASCII, or ideographic characters or a mixture of both. To reduce the size of the font memory, a translator memory is provided for converting non-sequential numbers representing the characters of a standard internal code used by the PC into a sequence of consecutive numbers for addressing the font memory.

Abstract: A system for creating font memory banks to be used as look-up tables in a character generator of a dot matrix printer. This system involves the combination of memory and operator input whereby memory banks of individualized fonts may be designed. The print characteristics of the type of printer to be used are simulated to facilitate the font creating process.

Abstract: PURPOSE:To enable characters of a desired size to be obtained, by providing a font-converting means for forming a font of a desired size by applying a conversion rule to a fundamental font, in a line printer. CONSTITUTION:First, when a conversion ratio is externally designated to a font conversion ratio designating part 11, a conversion rule forming part 2 forms a conversion rule 3 by using a fundamental conversion rule 1. For example, when a conversion ratio of 1/4 reduction is designated, the fundamental conversion rule for 1/2 reduction is applied two times, then a font-converting part 5 applies the conversion rule 3 to the fundamental font 4, and a desired font is outputted as a converted font 12, whereby characters of a desired size can be obtained. Accordingly, the fundamental font can be easily converted to a desired size, and the converted font can be outputted.

Abstract: PURPOSE:To increase printing speed and improve the quality of printing by writing a print em code according to the font of the letter into the memory of a character generator and by effectively utilizing the entries for printing. CONSTITUTION:A letter font area a, a print em code area b and other necessary conversion code areas e.g. the areas which include the area for descender row code etc. are provided in a letter font memory of a character generator where letter font codes (a) are memorized, and print em codes (b) are memorized together with letter font codes. When a letter font is read out, a print em code is also read out and utilized for printing. For instance, a print em is appropriate as an information for switching between one way printing and both way printing of a dot printer.

Abstract: A method of data compression which allows an enlarged font of complex characters to be produced by scaling from data representing a stored font of complex characters is disclosed. The scaling procedure involves the insertion of horizontal and vertical lines into the stored font to effect vertical and horizontal expansion, respectively, of the stored fonts. These lines are inserted so as to preserve the basic shape of the characters according to the following procedure. First, the dot matrix of each character is partitioned into sections, each containing a very pronounced and recognizable portion of the character. Then a decision is made in which sections to insert lines so that enlargement is attained without distorting the basic overall shape of the character. Next, a decision is made where in the sections the lines are to be inserted. Finally, a decision is made as to what the inserted lines are to look like. The results of these decisions are stored with data representing the stored font as side information so that an enlarged version of the font can be generated on the fly without need of arithmetic processing. A refinement of this basic technique additionally stores a sparse matrix containing the error of the generated matrix as compared with the original one. This additional information permits the generation of the exact duplicate of the original font.

Abstract: PURPOSE:To send out many letter species by a method in which when font patterns of KANJI etc, to be sent out are not found in the font pattern RAM, transference is demanded on the host side and rewriting is dynamically made CONSTITUTION:In case where the font pattern of letters, eg, KANJI, etc, to be sent out is not found in a font pattern memory 224, the transference of the font pattern is demanded on the host side 202 by a controller 222 When the font pattern is received, the font pattern, together with an age information to show the time of writing to RAM provided in the memory 224, is written In the determination of location in the RAM in which the pattern is to be written, location in the RAM is orderly investigated by hashing, and when the location is vacant or age information by age counter stored correspondingly to the location is older than a given value, the font pattern is written in there and corresponding age information is rewritten

Abstract: PURPOSE:To enable the fabrication of printing data wherein the type face of a standard font is controlled to an arbitrary type face from the outside, by applying comparative operation to the built-in standard font having a fundamental font mounted therein and the change informations stored in data memory. CONSTITUTION:The standard font stored in built-in standard font memory 1 is loaded to one character memory 2 by a printing order. The change information font from an external interface is stored in a font command register 4 through a data loading control part 3. The longitudinal and transverse dot constitution of the change information font and the standard font of the one character memory 2 forms relative relation. Both of the standard font and the change information font are inputted to a font operation circuit 5 and the standard font stored in the one character memory 2 receives comparative operation by the data constitution of the font command register 4 to be controlled to a desired type face and is stored in printing memory 6 as printing data.

Abstract: PURPOSE:To improve the operability by setting a character font mode having the highest operating frequency as a default value and converting it automatically after the execution of input by other character font mode to decrease the number of times of operation of character font mode conversion. CONSTITUTION:While an initializing key on a keyboard 1 is depressed in the setting of the initializiag mode, a character font mode designation key having the highest using frequency is depressed. Thus, a default value of the depressed mode is set to a mode set section 2 as the initial mode in this way. When the switch of the initial mode is turned on at the same time so as to initialize the mode. In conducting Kana (Japanese syllabary)-Kanji (Chinese characters), the character font mode is processed other than the set character font mode and when an execution key is inputted at the end of the former processing, the character font mode is converted automatically into the initial mode. Thus, the mode is converted automatically to the initialized mode without any key operation of the operator, the number of times of operation of character font mode conversion, allowing to improve the operability.

Abstract: PURPOSE:To attain copying for each font pattern between external memory means by reading the photopatterns to a pattern temporary memory part from the 1st external memory means and then writing them to the 2nd external memory means. CONSTITUTION:The addresses of font patterns stored in the 2nd external memory means 10 are fed by means of ten-key provided at an input part 1. At the same time, an execution key is fed. The font patterns stored in the means 10 are read 10 are read out within a pattern temporay memory part 14. Then the address of the stored destination is fed with the ten-key together with the execution key. Therefore the font patterns stored in the part 14 are read out and stored at designated addresses of the 1st external memory means 9.

Abstract: PURPOSE:To specify a person who leaks a copy of information from the information when the information is copied and leaked by assigning copy areas for respective specific persons concerned who can refer to the information recorded in a prescribed area. CONSTITUTION:For example, when an original document is written with Ming type Chinese character (commonly used font), copied information is supplied to a distribution destination (copying person) A so that ''shu'' (end) is changed in form into Gothic. The form of ''toi'' (question) and ''sei'' (manufacture) is changed into Gothic for a copying person B, and ''den'' (electric) is changed into Gothic for a copying person N. Consequently, words specified differently for respective plural copy areas are made different in form from other words. When the form is changed, one-bit font information is given to the head of, for example, a character symbol code and the information is inverted to select the form of character symbols to be copied.

Abstract: By switching a character generator between two different dot patterns or fonts for each character in response to the state of a normal/reverse mode control the legibility of reverse-video fonts is increased. In the reverse font (32), each vertical stroke has two (or more) consecutive dots in the vertical strokes wherever the normal font (31) has a single dot.

Abstract: PURPOSE:To print without missing of information by providing plural font memories different in line character number corresponding to the edition pattern of a document outputted from an external equipment, and generating warning when the document information is inadequate thereto. CONSTITUTION:A document is generated by a prescribed edition pattern by operating a keyboard in a personal computer. In giving a command so as to transmit the document to a facsimile equipment 1n, a command signal to select an 80-character font memory 7 or a 132-character font memory 8 at first, and a character code are transferred next. A CPU6 judges to show the number of lines of the document in the facsimile equipment 1n, and a sensor 3 detects the paper size of a paper feed cassette to check the propriety of the both. When the both are matched, the document is printed out based on the document code inputted sequentially and when not matched, the warning and display representing it are conducted.
