    • Code data is converted to an intermediate code data, the intermediate code data is stored in an intermediate code buffer memory, the intermediate code data is converted to picture element data, the picture element data is stored in a page buffer memory and the picture element data is transmitted to a page printer. After the code data is stored in the intermediate code buffer memory, control code data indicating one page part finishing is received in the intermediate code buffer memory buffer, and the printing process preparation signal is outputted to the page printer. When code data is converted to intermediate code data, a format of the code data is judged, to determine whether a conversion processing from the intermediate code data to the picture element data, corresponding to the code data, requires a processing time which extends beyond a predetermined time limit and if such is true the intermediate code data corresponding to the code data is immediately converted to picture element data and stored in the page buffer memory. A high speed processing time can be obtained. A lifetime decrease in the page printer can be restrained effectively. An improved image output system having a high accuracy and a high reliability can be obtained.
    • 将代码数据转换为中间代码数据,将中间代码数据存储在中间代码缓冲存储器中,将中间代码数据转换为图像元素数据,将图像元素数据存储在页面缓冲存储器中,并且图像元素数据 被传送到页面打印机。 在将代码数据存储在中间代码缓冲存储器中之后,在中间代码缓冲存储器缓冲器中接收指示一页整理的控制代码数据,并将打印处理准备信号输出到页打印机。 当代码数据被转换为中间代码数据时,判断代码数据的格式,以确定对应于代码数据的从中间代码数据到图片元素数据的转换处理是否需要延长超过 预定的时间限制,如果是这样,则与代码数据相对应的中间代码数据被立即转换为图像元素数据并存储在页面缓冲存储器中。 可以获得高速处理时间。 可以有效地抑制页面打印机的生命周期减少。 可以获得具有高精度和高可靠性的改进的图像输出系统。

    • A thermal printer including a thermal printer and a thermal head wherein a clearance between the platen and the thermal head is not less than a maximum diameter of one roll of an ink filled ribbon set by a thermal head driving motor. A ribbon cassette is moved to a printing position and, after a printing operation has been completed to another ribbon cassette. A guiding arrangement for positioning the ribbon cassettes in predetermined positions is adapted to be rotatably driven by a ribbon cassette motor and a plate for supplying the ribbon cassette and receiving the ribbon cassetts. The plate is joined to a take-up end portion of the ribbon cassette and the guiding arrangement is adapted to be moved in the forward and rearward direction for supplying the ribbon cassette and receiving the ribbon cassette by a transfer belt which can be moved by a cassette-moving motor. The guiding arrangement is adapted to be changed by withdrawing from the ink ribbon to another ink ribbon by a fixing member which is adapted to be moved by a ribbon cassette motor. A plurality of ribbon cassettes can be selectively used so that an unnecessary feeding of the ink ribbon can be avoided.
    • 一种包括热敏打印机和热敏头的热敏打印机,其中压板和热敏头之间的间隙不小于由热打印头驱动电机设定的一卷墨水填充色带的最大直径。 色带盒被移动到打印位置,并且在打印操作已经完成到另一个色带盒之后。 用于将色带盒定位在预定位置的引导装置适于由色带盒电机和用于供应色带盒并接收色带盒的板旋转驱动。 板被连接到色带盒的卷绕端部,并且引导装置适于沿前后方向移动,以供给色带盒并通过转印带接收色带盒,该转印带可以被移动 盒式电动机。 引导装置适于通过由适于由色带盒电机移动的固定构件从色带退出到另一个色带来改变。 可以选择性地使用多个色带盒,从而可以避免色带的不必要的进给。
