Abstract

PURPOSE:To easily grasp the using method of a printer without its manual by storing printer operation instruction information in a control part and printing out specific operation information from an operation part. CONSTITUTION:When print data from a host device is printed normally, the control part 1 receives the print data by a port 7 and stores it in a RAM 5. Then character pattern information corresponding to the code of the print data is read out of a character pattern memory 8 and supplied as print dot information to a print dot data sending part 10, so that the data is printed. Then when the printer operation instruction information is printed, the control part 1 reads print information out of a ROM 9 stored with the printer operation instruction information instead of receiving data from the host device on receiving a print indication from an operation part 3, and the stores it in the RAM 5. Then the character pattern information corresponding to the code stored in the RAM 5 is read out of the memory 8 and sent out to a recording part 2 in the same mode as the normal printing mode.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a printing device (hereinafter referred to as a printer) that receives encoded character code data from a host device such as a computer and prints characters, figures, etc. )K, particularly regarding the printing function of a printer.

[Conventional technology]

Conventionally, this type of printer has a function of printing characters and figures based on data received from a host computer, etc., and also has a so-called test print function of specific print patterns for testing and diagnosis. It is normal to have one. As for other printing functions, some high-end printers have a function that prints the status of setting switches inside the printer and internal information.

[Problem that the invention seeks to solve]

When using the above-mentioned conventional printer, please refer to the instruction manual attached to the printer device for information on the character data format that should be given to the printer and the data format of the control codes that control the printer's operation. It was based on the document. In this case, if the manual is not at hand, printing data cannot be created, which often causes inconvenience.

[Means for solving problems]

The features of the present invention are to incorporate information such as the printer's printing function and print data format into the printer or add a cartridge or the like to the printer; It has the ability to print out.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a printer according to an embodiment of the present invention.

Reference numeral 1 denotes a control unit of the printer which decodes print information received from a host device such as a computer and controls printing in the recording unit 2. The recording section 2 is a module that prints on paper under the control of the printing control section 1. Further, 3 is an operation section. The present invention largely relates to this print control section 1, and a more detailed block diagram of this print control section 1 is shown in FIG. The print control unit of this embodiment is controlled by a microprocessor, including a microprocessor 4, a read-only memory (hereinafter referred to as ROM) 5 in which the program of this microprocessor 4 is stored, and a write/readable recording element (hereinafter referred to as RAM). 6. A host device interface port 7 that exchanges print information, control, status information, etc. with a host device; character pattern memory 8 that stores the print character pattern of the printer; and a readout device that stores information explaining how to use the printer of the invention. It consists of a dedicated memo IJ (ROM) 9 and a print dot data sending section 10 that sends a print pattern to the recording section 2. The operating section shown in FIG. 1 and 3 is also connected to the microprocessor via the operating section interface port 11.

The operation will be explained using these figures below. When normally printing print data from a host device, the print data is received at port 7 and stored in the R, AM5, and K-carriers. Then, corresponding character pattern information is read out from the character pattern memory 8 according to the code of the print data, and the print dot information is given to the print dot data sending section 10 for printing.

Next, when printing information explaining how to use the present invention,
When the print instruction is received from the operation unit 2, the ROM 9 stores the operation instruction information instead of receiving it from the host device.
The print information is read from and stored in RAM5.

Thereafter, the operation of reading character pattern information corresponding to the code stored in the RAM 5 from the character pattern information memory 7 and sending it to the recording section is the same as in the normal printing mode.

FIG. 3 shows a printed example of the operation instruction information.

〔Effect of the invention〕

As explained above, the present invention stores usage instruction information in the printer and enables the printer's manual to be printed out by a specific operation from the operation unit. This has the effect that you can easily learn how to use it even if you do not have it at hand.

[Brief explanation of the drawing]

FIG. 1 is an overall configuration diagram of a printing apparatus according to an embodiment of the present invention, FIG. 2 is a detailed block diagram of the printing apparatus according to an embodiment of the present invention, especially the control section, and FIG. 3 is a printing apparatus according to an embodiment of the present invention. This is an example of a print result of usage operation information output by the device.

Claims (1)

[Claims] In a printing device that prints characters, figures, and images based on codes from a higher-level computer, in addition to the function of printing characters, figures, etc. using codes from a higher-level computer, it also has the function of printing characters, figures, etc. based on codes from a higher-level computer. A printing device comprising: a read-only memory that stores code data in the same code data format as the code data from the device; and an operation unit that instructs to print out the usage operation information independently of a host device. .
