Abstract

PURPOSE:To make it possible to obtain such a print output as to permit instantaneous visual recognition of a repagination, if any, in dumping received data by a method wherein upon reception of a repagination code during dumping received data, an operation of printing the received data momentarily stored at that moment and a repaginating operation are carried out based on an output from a means for discriminating the repagination code. CONSTITUTION:Data sent from a host device is written into and held in a reception buffer 1, and it is judged by a decoder 2 whether the data is a repagination code. When the data is judged as the repagination code, it is compared in a character editing part 4 with a character pattern supplied from a character pattern generating part 3, and is transferred to a printing-controlling part 5. Simultaneously, a printing and line feeding instruction 2b is sent from the decoder 2 to a repagination controlling part 6, which calculates a required line feed quantity, and outputs a printing and line feeding instruction 6b to the printing-controlling part 5. The controlling part 5 forcibly performs a printing operation and a line feeding operation, even during dumping the received data.

改頁制御部６とから構成されている。a decoder 2 that determines whether the read data from the reception buffer 1 is a page break code; a character pattern generator 3 that generates a character pattern corresponding to the received data;
The character collection parts 4 and 5 refer to the data 2a other than the page break code of the decoder 2 with the character pattern input from the character pattern generation part 3 and output it to the print control part 5I.
a printing control unit 5 that electrically drives the mechanical unit to print and also performs a page feed operation; and an output 2b that corresponds to the page break code determination of the decoder 2. and a page break control section 6 which in response causes the print control section 5 to make a page break operation sound.

つぎに動作について説明する。Next, the operation will be explained.

まず１図示しない上位ｆ２［よシ送られてき之データは

を繰返えす。If it is not a page break, the data is sent from the one-character pattern generation section 3 to the character editing section 4, referred to as a circle character pattern, and sent to the print control section 5. Then, decoding and character editing processing is performed until data for one line of valid characters is collected, and when data for one line of effective characters is collected, printing operation, automatic line break, and decoding and character editing processing are repeated again. .
