摘要： Methods enabling the use of an office printer connected to a microcomputer in order to print legitimate postal marks. It uses a cartridge of special fonts in which there are stored the franking marks according to the standards laid down for the printer. A known security component is provided, on the one hand to protect access to the memory contained in the cartridge and, on the other hand, to perform the computation, for each printing of a franking mark, of a security mark that contains encrypted information elements that are readable by the postal authority, enabling the franking mark to be authenticated. It provides for the elimination of specific franking machines and limits the handling operations to the handling of a small-sized cartridge.

摘要： A computer downloads rasterized font characters to a connected printer and employs a method which enables a rendering of large character sets by the printer, even though the printer is not designed to internally handle such large character sets. The method enables the computer to control allocations of memory in the printer for storage of font data. Initially, the computer arranges for the printer to allocate an initial portion of memory for storage of font data. A printer driver within the computer then analyzes data segments to be sent to the printer to determine if a respective data segment is text-related data; graphics-related data or raster data. If it is determined that text-related data is to be sent to the printer, it is next determined if the printer stores font data to enable a printing of a character designated by a current character-defining data segment. If the printer does not store the necessary character, the method causes, if necessary, the printer to allocate further memory for storage of the additional font data to be supplied by the computer. The computer further controls the printer to revise the portion of memory allocated for the storage of font data, if either graphics-related data or raster data is being sent to the printer.

摘要： An output apparatus having a dot matrix memory and a non-dot-matrix memory, and a method applicable to such an apparatus, in which the dot matrix memory stores an externally entered download font for converting code data into dot matrix data, and in which the non-dot-matrix memory stores non-dot-matrix data for converting code data into non-dot-matrix data and then into dot matrix data. When code is received, the two mentioned memories are controlled so as to have priority in the order: dot matrix memory, then non-dot-matrix memory, to obtain a desired dot pattern in response to the received code data.

摘要： Font character data is maintained in a cache memory in bit map form. Each character is identified a unique identifier (ID) value. The printer searches the cache memory only by ID value to determine the presence of a character in the cache. Pointer tables are avoided. A list is maintained of characters recently employed by the printer and is arranged so as to enable determination of a ranking of usage among the listed characters in cache. When a new character is requested by the printer, the cache is initially searched to determine if the character is present therein. If the character is found, it is immediately accessed and its identifier is placed at the head of the usage list. Other characters are pushed down in the list. The least recently used character in the list (at the list's bottom) is removed unless it is being employed in a print action, in which case, a next higher character in the list is examined to determine if it should be removed based upon both usage criteria and requirement for a page being processed.

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.

摘要： An output device is enabled to obtain character descriptions for use in raster scanning characters which belong to a common character font. Character descriptions are stored in an external device which is linked to the output device by a communication channel. Character codes are received at the output device which identify characters to be outputted. A raster image of the characters to be outputted is set up. In the course of setting up the raster image, information corresponding to the character codes is sent from the output device to the external device via the communication channel. In response to the character codes sent from the printer to the external device, corresponding character descriptions are sent from the external device to the output device via the communication channel.

摘要： Because laser printers are capable of rendering only a maximum number of characters per unit time, pervious printer would pre-render the entire page prior to print the page. This pre-rendering process greatly increases the memory requirements. To overcome this problem, there is provided a method for reducing memory requirements in a laser printer when printing a page of characters. First, the page is divided into a series of strips. Next, the entire page is scanned strip by strip for any strips that contain an excess number of characters, where the excess number is that number of character that exceeds the maximum number the printer can render in the given time. Assuming a complex strip is found, any common characters in the complex strips are prerendered. If, after pre-rendering the common characters any strip is still complex, then the excess characters are pre-rendered. Finally, each character in a strip is rendered when the printer is ready to print that strip, if any character in the strip was pre-rendered then it is retrieved from memory. Thus, the present invention renders many of the characters while the page is being exposed. Therefore, the printer can start the exposure process sooner and with significantly lower memory requirements.

摘要翻译： 因为激光打印机能够在每单位时间内只能呈现最大数量的字符，所以透明打印机将在打印页面之前预渲染整个页面。 这种预渲染过程大大增加了内存需求。 为了克服这个问题，提供了一种在打印字符页时减少激光打印机中的存储器要求的方法。 首先，页面分为一系列条。 接下来，整个页面按条带逐条扫描，包含超出字符数的条带，其中超出的字符数超过了打印机在给定时间内可以呈现的最大数量。 假设找到一个复杂的条，复合条中的任何常见字符都将被预渲染。 如果在预渲染公用字符之后，任何条纹仍然很复杂，那么多余的字符是预呈现的。 最后，当打印机准备好打印该条时，条带中的每个字符都将被渲染，如果条带中的任何字符都被预先渲染，那么它将从内存中检索。 因此，本发明在页面被曝光时呈现许多字符。 因此，打印机可以更快地开始曝光过程，并且显着降低内存要求。
