Abstract

PURPOSE:To display dot information transferred from a printer to a host apparatus by providing a function of developing code data received from the apparatus according to the information, and a function of transferring the developed information to the apparatus. CONSTITUTION:A bus line 12 connects a host apparatus controller 10 to a display 11, and a bus line 13 connects the controller 10 to a printer 14 having a developing function unit 15 and a transferring function unit 16. Here, code data are applied from the controller 10 to the printer through the line 13, a character pattern corresponding to the data is developed by the unit 15 according to the information, the developed information is transferred to the controller 10 through the line 13 by the unit 16, and displayed on the display 11 through the line 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printer that stores character patterns as dot information.

Conventional technology Conventionally, in this type of printer, the code data given from the host device 1 is developed into dot information and then transmitted only to the printing function within the printer, and the exact format to be printed is determined by the host device. I couldn't figure it out. Problems to be Solved by the Invention Therefore, when confirming the print format on a display screen, it is necessary to simulate and display the printer's operation using code data within the display device, and to control line breaks, etc. that the printer has. The disadvantage is that it has to process the code or dot control function code. The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new printer which makes it possible to eliminate the above-mentioned drawbacks inherent in the conventional technology. Means for Solving the Problems In order to achieve the above object, the printer according to the present invention has a function of developing code data received from a host device according to dot information, and a function of transmitting the developed dot information to the host device. It has Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. Referring to FIG. 1, reference number 10 is a host device control unit;
11 is a display, 12 is a bus line, 13 is a bus line, 1
4 is a printer, 15 is a development function section, and l6 is a transfer function section. Here, the code data reaches the printer 14 from the host device control unit 10 via the bus line 13, and the development function unit 15 develops a character pattern corresponding to the code data according to the dot information, and the developed dot information is The transfer function unit 16 transfers the data to the host device control unit 10 via the bus line 13 and displays it on the display 11 via the bus line 12.

Effects of the Invention As described above, according to the present invention, by providing the printer with the expansion function section and the transfer function section, it is possible to obtain the effect that dot information transferred from the printer to the higher-level device can be displayed on the display.

In addition to displaying the dot information transferred from the printer on the display, it can also be used as a facsimile machine! It is conceivable that the information can be sent to the other party's facsimile machine via the fax machine.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing one embodiment of the present invention.

Claims (1)

[Claims] In a printer that holds the character pattern corresponding to each code as dot information, develops the code data received from the host device according to the dot information, and prints the character corresponding to the code, the character of the one line sentence to be printed is dotted. A printer characterized by having a function of developing information and transmitting it to a host device.
