Abstract

PURPOSE:To enable an operator to easily know the internal state of a printer at a necessary time, by detecting the signal from the operator and outputting the internal state as a printing result. CONSTITUTION:A signal detection part 1 detects the signal generated when an operator operates the switch of an operation panel if necessary and transmits the information thereof to an internal state code converting part 2 and a printing data editing part 3. The printing editing part 3 process the data receiving from an upper rank apparatus till then at first at the point of time when receives said information and subsequently processes the printing code generated in the internal state code converting part 2 to print an internal state. Therefore, because the internal state can not be known easily, the claim investigation to a printer of the development of software controlling the printer becomes easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and particularly to a printing device that has the ability to print the internal state at that point in time by receiving a certain stray signal from the outside.

[Conventional technology]

Conventionally, there has been no means for easily knowing the current internal state of a printing device, and methods have been taken such as estimating it from the printing results using special development tools.

[Problem that the invention seeks to solve]

The above-mentioned conventional printing device has the disadvantage that it takes a large amount of man-hours to investigate complaints about the printing device and to develop software to control the printing device, since the internal state cannot be easily known.

[Means for solving problems]

The printing device of the present invention has means for detecting a signal from the outside and means for converting an internal state into a print code by receiving the signal and printing the code.

〔Example〕

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

FIG. 1 is a professional model showing an embodiment of the present invention. A signal detecting section 1 detects a signal generated by an operator operating a switch on a control panel in response to a busy event, and transmits the information to an internal status code converting section 2 and a print data editing section 3. When the print data editing unit 3 receives this information, it first processes the data received from the host device up to that point, and then prints the internal status by processing the print code generated by the internal status code conversion unit. do.

〔Effect of the invention〕

As explained above, the present invention detects a signal from an operator and outputs the internal state as a printing result, thereby making it possible for the operator to easily know the internal state of the printing device when the printing device is fully loaded. This has the effect of significantly shortening the development time for software that controls research or printing devices.
