摘要： A printer is shown for printing a large number of symbols from a standardized set of symbols wherein each symbol has an associated code word that identifies the symbol within the set. The pixel data for each symbol in the standardized set is stored in a memory at addresses that are different from the code word identifying the symbol. The printer includes a microprocessor control circuit that receives input data including a code word identifying a symbol to be printed from an input device. The microprocessor control circuit includes a direct memory access controller for controlling the transfer of data from the symbol memory to an output image buffer. Hardware is provided to generate the addresses to the symbol memory necessary to read pixel data for a given symbol out from the memory in response to an output code word thereby eliminating the need for a large look-up table.

摘要： A novel method and system for operation in combination with a laser printer for expanding its character and typeface selection capability. The sequence and operation for this method and system include dividing a list of characters to be printed into a plurality of character groupings or collections, storing these character groupings or collections in a plurality of different memories or memory sites, and providing an input command signal to these memories or memory sites which corresponds to a selected character desired to be printed. The different memories or memory sites are addressed starting first with the memory or memory site storing the largest character grouping or collection having the most frequently used characters therein and then addressing the different memories or memory sites in sequence to or toward the memory or memory site storing the smallest number of less-frequently used characters therein. In this manner, the memory storage capability and computational speed of the laser printer are maximized, and the price/performance figure of merit and reliability of the printer are also maximized.

摘要： A character generator which converts character code words into data items, namely column code words (C code), for controlling a dot matrix output unit, is disclosed. The character code word is presented to an address memory circuit which generates a ten-bit-long column address (CAD) that identifies the locations of the column code words within a separate data storage unit. The address memory circuit includes two memory units (PROM 1, PROM 2) which store only the first eight bits of respective column data addresses, while an additional memory unit (PROM 3) stores the remaining two bits of the respective column data addresses. A multiplexer (15) is used to select the correct two bits of each respective column data address from an eight-bit word output by the additional memory unit (PROM 3) at the same time an eight-bit address is being output by one of the first two memory units (PROM 1, PROM 2). The ten-bit address thus output by the address memory circuit is applied to the data storage unit, which may be built up by using commercially available programmable read-only memory units (PROM 4, PROM 5, PROM 6), as may the address memory circuit. For a further utilization of the storage capacity of the additional memory unit (PROM 3) of the address memory circuit, the first eight bits of additional column data addresses may be stored therein. These first eight bits are then fed to the data storage unit by way of a switching amplifier (14), with the multiplexer (15) supplementing the additional column data addresses with two bits which are zeros in order to produce a ten-bit address.

摘要： A printer once stores input data in a buffer memory and then sequentially reads them out for printing. Whether the input data is predetermined one is determined and, based on the result, the sequence of input data stored in the buffer memory is changed. Even in an auto-back mode of operation, the printer prevents a host system associated therewith from erroneously detecting a printer error to stop a job thereof.

摘要： According to a print control apparatus of a printer which has a line buffer, when one-line data transmitted from a host CPU includes a character and a figure, a print and line feed controller causes a character image generator to access a character pattern memory so as to write the readout a character image in the line buffer. The print and line feed controller causes a figure image generator to generate a figure image which is then ORed-written on the character image. As a result, one-line character and figure data can be printed with one scanning operation. Figure data parameters are stored in the parameter area in the internal memory. Every time printing of a page is performed in units of predetermined dot widths, the parameter corresponding to the figure image developed into the line buffer is deleted from the parameter area. The next parameter is then stored in the parameter area.

摘要： A character image processing apparatus so adapted that when a typeface and size are specified at generation of a character image, a font of a specific typeface and of a size within predetermined selection limits of a specified size is retrieved from pre-rasterized fonts already developed as bitmap data and stored. In a case where a character image is generated from this font, the character will be generated at a position offset from the position the character of the specified size would have originally occupied. Accordingly, position is corrected in such a manner that the center of the position which a character would have originally occupied and the position of the center of the character generated from the pre-rasterized font will coincide. Further, the selection limits are decided using sizes midway between a stored pre-rasterized font and character sizes one size larger and one size smaller than that of this pre-rasterized font as boundaries.
