摘要： Photographic printer of the type employed for printing according to the monoline technique on photosensitive paper (18), the printer being fed from a wound roll (11) of continuous photosensitive paper (18) and comprising an assembly (12) for the feeding and positioning of the paper (18), a printing device (13) and shearing means (14), the feeding and positioning assembly (12) comprising a first pair of opposed loading rollers (15a, 15b) and a second pair of opposed drawing rollers (16a, 16b) defining a plane of running (19) of the photosensitive paper (18), at least the second pair of drawing rollers (16a, 16b) being at least momentarily actuatable independently step-by-step and being capable of two-way motion, a buffer-stock chamber (20) being included in an intermediate position between the pairs of rollers (15a, 15b, 16a, 16b) and being located in cooperation with the plane of running (19) of the paper (18), the entry of the buffer-stock chamber (20) cooperating at least momentarily with means (21) supporting the paper (18). Digital-printing method performed with the above photographic printer (10) and comprising a preliminary step of loading the paper (18) and a printing step, the printing step including the steps of:
feeding of the paper (18) by means of the first pair of loading rollers (15a, 15b) and by the second pair of drawing rollers (16a, 16b) along a segment equal to the length of the photograph to be printed; clamping of the first pair of loading rollers (15a, 15b); backward drawing of the paper (18) by the second pair of drawing rollers (16a, 16b) actuated with controlled steps and simultaneous printing by the printing device (13), the paper (18) being arranged in the buffer-stock chamber (20) according to a loop having a substantially U-shaped conformation due to the weight of the paper (18); forward movement of the printed paper (18) and shearing thereof.-

摘要： Photographic printer of the type employed for printing according to the monoline technique on photosensitive paper (18), the printer being fed from a wound roll (11) of continuous photosensitive paper (18) and comprising an assembly (12) for the feeding and positioning of the paper (18), a printing device (13) and shearing means (14), the feeding and positioning assembly (12) comprising a first pair of opposed loading rollers (15a, 15b) and a second pair of opposed drawing rollers (16a, 16b) defining a plane of running (19) of the photosensitive paper (18), at least the second pair of drawing rollers (16a, 16b) being at least momentarily actuatable independently step-by-step and being capable of two-way motion, a buffer-stock chamber (20) being included in an intermediate position between the pairs of rollers (15a, 15b, 16a, 16b) and being located in cooperation with the plane of running (19) of the paper (18), the entry of the buffer-stock chamber (20) cooperating at least momentarily with means (21) supporting the paper (18).
Digital-printing method performed with the above photographic printer (10) and comprising a preliminary step of loading the paper (18) and a printing step, the printing step including the steps of:
feeding of the paper (18) by means of the first pair of loading rollers (15a, 15b) and by the second pair of drawing rollers (16a, 16b) along a segment equal to the length of the photograph to be printed;
clamping of the first pair of loading rollers (15a, 15b);
backward drawing of the paper (18) by the second pair of drawing rollers (16a, 16b) actuated with controlled steps and simultaneous printing by the printing device (13), the paper (18) being arranged in the buffer-stock chamber (20) according to a loop having a substantially U-shaped conformation due to the weight of the paper (18);
forward movement of the printed paper (18) and shearing thereof.摘要翻译： 用于根据单晶技术在感光纸（18）上印刷的类型的照相打印机，打印机由连续感光纸（18）的卷绕辊（11）进给，并且包括用于进给和定位的组件（12） 的纸张（18），打印装置（13）和剪切装置（14），进给和定位组件（12）包括第一对相对的加载辊（15a，15b）和第二对相对的拉伸辊 限定感光纸（18）的行进平面（19）的至少第二对牵引辊（16a，16b）至少可以一步一步地致动， 缓冲储存室（20）被包括在成对的辊（15a，15b，16a，16b）之间的中间位置并且与纸（18）的运行平面（19）配合定位， 缓冲储存室（20）的进入至少暂时配合 具有支撑纸张（18）的装置（21）。 使用上述摄影打印机（10）执行的数字打印方法，包括装载纸张（18）和打印步骤的预备步骤，所述打印步骤包括以下步骤：通过第一 一对装载辊（15a，15b）和第二对牵引辊（16a，16b）沿着与要打印的照片的长度相等的段; 夹紧第一对加载辊（15a，15b）; 通过被控制步骤致动并由打印装置（13）同时打印的第二对牵引辊（16a，16b）向后拉伸纸张（18），纸张（18）布置在缓冲储存室（20）中 ）根据由于纸（18）的重量而具有大致U形构造的环; 打印纸（18）的向前运动和剪切。
