    • Additive information for restoring the contour of an image is generated and embedded in the image data. The format of the additive information is determined beforehand. When a hard copy is produced, the additive information is extracted from received image data. The additive information is for example vary small characteristic points of a density different from the density assigned for image data and arranged inside the contour. The image data is restored according to the extracted additive information. The additive information can be generated for example from the code information for generating patterns such as control points data of an outline font. For a half-tone image, a plurality of density bands is assigned to the additive information. A read error is detected by comparing the restored image with the received image data.
    • 生成用于恢复图像轮廓的附加信息并嵌入在图像数据中。 预先确定添加剂信息的格式。 当产生硬拷贝时,从接收的图像数据中提取添加信息。 添加剂信息例如改变与分配给图像数据的浓度不同的密度的小特征点并且布置在轮廓内。 根据提取的附加信息恢复图像数据。 附加信息可以例如从用于生成诸如轮廓字体的控制点数据的图案的代码信息生成。 对于半色调图像,将多个密度带分配给添加信息。 通过将恢复的图像与接收到的图像数据进行比较来检测读取错误。

    • A printing system comprising a data processor, a printer, and an ID code transmitter for allotting an ID code to a data file for distinguishing the data file from others. An input device is mounted on the printer for providing the ID code to the printer before a printing process is executed. The printer executes the printing process in response to the ID code provided thereto and on the basis of the data file to which the ID code has been allotted. The invention is particularly adapted for preventing the user of the data processor from obtaining a printout on the basis of another user's data file by mistake.
    • 一种打印系统,包括数据处理器,打印机和用于将数据文件与其他数据文件区分开的ID代码的ID代码发送器。 输入装置安装在打印机上,用于在执行打印处理之前向打印机提供ID代码。 打印机响应于提供给其的ID代码,并且基于已经分配有ID代码的数据文件来执行打印处理。 本发明特别适用于防止数据处理器的用户错误地基于另一用户的数据文件获得打印输出。
