Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a document editing and printing device, and particularly to improving safety and printing operability when a printer cover of a print head section is opened during printing. This invention relates to an improved document editing and printing device.

[Conventional technology]

Wire dot printers, which are most often connected to personal computers, Japanese word processors, and other printing devices, are desired to shorten printing time from the perspective of improving business efficiency. Therefore, there is a strong tendency for the printing speed of printing devices to increase.

As printing devices become faster, the speed at which the print head moves during printing naturally also increases, and if the cover of the printing device is opened during printing and a hand is accidentally inserted into it, there is a risk of injury. Furthermore, if foreign matter gets inside, there is a possibility that the device will malfunction.

Therefore, the printing station 'iA' is provided with a processing means that stops the printing operation and places the printing apparatus in an off-line state to ensure safety when the cover of the printing apparatus is opened.

[Problem to be solved by the invention]

In systems such as Japanese word processors (hereinafter referred to as WP) that use a printing device in an online state, if the printing device goes offline, it is treated as an abnormal state, so the printer cannot be used again. When the printer goes online, it is common to eject the paper and wait to receive print data in order to initialize the printer. Naturally, the data that is being printed is not retained and the printing operation is restarted from the beginning. I need to start over.

This is because if you open the cover by mistake or open the cover to check whether printing is being performed correctly, the print data that was in the middle of printing will be lost and you will have to start over from the first page. It is very difficult to operate, such as not being able to
There is also an inconvenience that printing paper is wasted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document editing and printing device that can eliminate the above-mentioned disadvantages of the prior art and achieve both safety and improved operability.

[Means for Solving the Problem J The above purpose is to provide a print head, a cover that covers the print head, means for detecting the open/closed state of the cover, and stopping the printing operation of the print head when the cover is detected to be open. In a document editing printing device including a printing device having a means for printing, and a host device that gives a print command and print data to the printing device to execute printing, the generation of a signal indicating that the cover is opened causes a signal to be sent to the printing device. The processing means stops the transfer of the print data and holds the print data, and when the cover release signal is released, the transfer of the held print data is restarted and the printing operation starts from the line next to the line that has already been printed. This is achieved by providing a printing restart processing means for restarting printing.

Furthermore, the second aspect of the present invention is, in addition to the above-mentioned processing means, means for monitoring the time from generation to release of the cover open signal, and processing for executing error processing when the cover open signal continues beyond a predetermined time. It is characterized by providing means.

(Function) The printing device itself cannot determine whether or not the cover was opened by mistake during the printing operation, so it primarily stops the printing operation to ensure safety. According to the invention of No. 1, the printing operation can be restarted from the line following the line that has already been printed.

Improved operability is realized and no wastage of printing paper is achieved.Furthermore, according to the second invention, if the cover opening signal continues for more than a predetermined time, error handling is executed, so safety is not compromised.
