    • A dot-matrix printer having a print head (26) and a platen (27) allowing the head (26) to bring dot characters in normal printing mode and an extra-wide-margin printing mode. The printer has a microprocessor (20) which decides, in accordance with printing data from an external device, whether or not a wide dot character is to be printed at the left margin or right margin. When it decides that a wide dot character is to be printed at the left or right margin, the microprocessor controls a print head driver (25) so that the head (26) may print dot characters in the extra-wide-margin printing mode. The print head (26) can therefore print wide dot characters together with characters of ordinary width, neatly and clearly.

    • The preferred embodiment discloses an entirely new impact-type electronic printer using a rotary printing wheel which enables the ROM to store printing-type position data for dealing with respective printing types borne by the rotary printing wheel, hammer pressure data, and the spacing data respectively matching the designated printing types together with printing-type position data. The main CPU then draws out the printing-type position data, hammer pressure data, and the spacing data in response to the input data to allow the printer to execute the printing operation using the designated printing types in accordance with these data drawn out of the ROM, thus realizing distinctly clean printed characters. The unique system embodied by the present invention makes it possible for the controller to easily read important data from the ROM. In other words, since the control system reflecting the present invention allows the ROM to effectively store the printing-type position data, hammer pressure data, and the specifying data, the control system can, for example, securely read the data merely by executing the reading operations twice.
    • 优选实施例公开了一种使用旋转印刷轮的全新的冲击式电子打印机,其使得ROM能够分别存储用于处理由旋转印刷轮承载的各种印刷类型的打印型位置数据,锤压数据和间隔数据 将指定的打印类型与打印类型的位置数据匹配。 然后,主CPU然后根据输入数据抽出打印位置数据,锤击数据和间隔数据,以使打印机能够根据这些数据中的这些数据使用指定的打印类型执行打印操作 ROM,从而实现清晰的打印字符。 由本发明实现的独特系统使得控制器可以容易地从ROM读取重要的数据。 换句话说,由于反映本发明的控制系统允许ROM有效地存储打印类型位置数据,锤压数据和指定数据,所以控制系统可以例如仅仅通过执行控制系统来安全地读取数据 阅读操作两次。
