Abstract

PURPOSE:To easily change and register a message by providing an NVRAM and storing the message. CONSTITUTION:An error corresponding message, for example, such as 'please insert paper' or 'please exchange printing head', etc., from a host computer 1 is stored in an NVRAM6 for message to be provided in a page printer 2 and displayed through a control part 3 to a display part 4 with priority in correspondence to an error. By using this RAM6, it is not necessary to exchange a ROM itself like a case to use a ROM and the change and registration of the message can be easily executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device capable of displaying a message on a display.

[Prior Art] Conventionally, this type of device stores messages such as "Please insert paper" or "Please replace the print head" in the ROM as display messages required by the printing device. Then, the necessary message was read out from this ROM and displayed according to the status of the printing device.

[Problems to be Solved by the Invention] However, in this case, there is a problem in that if the message to be displayed is to be changed, the ROM must be converted. Furthermore, when attempting to select a desired message from among a plurality of messages, there is a problem in that the number of types of messages increases and a large storage area is required.

[Means for solving the problem] In order to solve this problem, the present invention makes it possible to change and register messages by providing an N V RAM for storing messages. be.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. A host computer 1 outputs print data and control commands, and has a program area PA that stores a control program according to the flowchart shown in FIG. 2 is a printing device capable of carrying out the present invention. 3 is a control section of the printing device, 4 is a display panel, 5 is a printing section of the printing device, 6 is an NVRAM for storing messages, and 7 is an operation panel.

The control of this embodiment having the above configuration will be explained with reference to the control flowchart shown in FIG. The data output from 1 is received in step S1.

It is determined in step S2 whether the received data is a message registration command, and if it is a registration command, the process proceeds to step S3; otherwise, the process proceeds to step S4. In step S3, the sent message is written into the NVRAM according to the type of error. Step S3 or S
It is determined in step S5 whether or not an error has occurred in step 4. If there is an error, the process proceeds to step S6, and if there is no error, the process proceeds to step S9. In step S6, it is determined whether or not the error message that has occurred is registered in the NVRAM. If it is registered, the process advances to step S8; if not, the process advances to step S7. In step S7, the message that the conventional printing device had is outputted to the display panel, and the process ends. In step S8, the message registered in the NVRAM is output to the display panel, and the process ends.

In step S9, it is determined whether or not the process has ended, and if the process has not ended, the process advances to step S1.

As explained above, this embodiment enables the following.

(1) Messages can be registered by the host computer.

(2) The registered message is output before the device's own message (i).

(3) If not registered, a device-specific message will be output.

[Other Embodiments] In the previous embodiment, the message was registered by the host computer, but it is also possible to set it by using the operation panel.

Further, although the display panel 4 is provided in the printing device 2, messages in the message NVRAM 6 may be displayed on a display device such as a CRT provided in the host computer 1.

[Effects of the Invention] As explained above, the present invention has the following effects.

(1) RO to change the display language of error messages
There is no need to change M.

(2) It is possible to enter the store's telephone number, etc.
