Description

[Detailed description of the invention]

The present invention relates to a printer device that is provided with a table for inputting form feed information in advance and that performs appropriate operations with simple commands from a central processing unit. Conventionally, as shown in Figure 1, the central processing unit HCPU
The printer PR of the terminal device DTE, which receives and prints information from the printer, had a complicated form feed operation. In other words, the paper format is standardized as much as possible for each user, but since various paper sizes are used, it is necessary to receive information in one format, create a format, and then use the next format. When creating a format,
Depending on the paper size and format, the number of line breaks required to change pages may be increased or decreased. For this reason, the operator may hold the actual paper in his hand and move it around, but if automatic line breaks are to be performed, the terminal device must send and store data on the number of line breaks for each format to the central processing unit in advance. Each time the central processing unit changes the format, it sets the printing device at the top position (home position) of the next page, so it prints a new line (NL)... (NL) and multiple line feeds (NL) until the next page form position is sent. For this reason, the printer of the terminal device only has to carry out a change of motion a plurality of times, for example, n times, according to the instructions as shown in FIG. In addition, in order to automatically perform the form feed operation, holes are sometimes provided on the outside of the paper and a photoelectric circuit is used when moving to the next form position.
If the paper is not perforated with great care, malfunctions may occur, and the processed paper will be expensive. SUMMARY OF THE INVENTION The purpose of the present invention is to improve the above-mentioned drawbacks, and to provide a printer device that is provided with a table for inputting form feed information in advance and that performs appropriate form feed operations with simple commands from a central processing unit. be. Embodiments of the present invention shown in the drawings will be described below. To explain using the configuration diagram shown in Fig. 2 and the message formula shown in Fig. 3 (b), LCU is the line control section, ILD is the initial load section, TBL is the table, CD is the code discrimination section, DTP is the data print drive section, PHD is the print head, LFC is the line feed control unit, CNT is the counter, PMT is the pulse motor, LCG is the line feed clock generator, C1, C2, C3 are the messages, NULL is the empty string,
C indicates the format type, and NL indicates a line feed (new line). When the terminal device DTE is powered on and starts operating, the initial load unit ILD accesses the central processing unit HCPU via the line control unit LCU and matches the number of line breaks corresponding to the format and form feed. Receive the table as data in advance and save it to the table TBL

Claims (1)

[Scope of Claims] 1. A printer that receives and prints information from a higher-level processing device, and moves paper from the current printing position to the beginning of a preset format based on a form feed command received from the processing device. In a printer device that performs line feed control that advances to a printed line, the printer side is provided with a code indicating the format type and a line feed that corresponds to the number of remaining lines for one page from the number of print lines specified for each format. an initial load unit that receives the code and the line feed number data from the processing device at system start-up and loads them into the storage device table; means for reading corresponding line feed number data in the table in response to the code and setting it in a counter; and subtracting the number of line feeds from the counter in response to a form feed command in the received message data; means for executing a line feed, and adding the format type code and form feed command after the last print data for one page of the message data transmitted from the processing device. The method is characterized in that the type code is decoded, line feed number data corresponding to the code is read from the table, and set in the counter, and continuous line feed is performed in response to the form feed command until the counter becomes zero. printer device.
