JPH05155115A - Apparatus indicating interior ready condition for printer - Google Patents

Abstract

PURPOSE:To make operations executable in accordance with interior conditions of a printer by providing a device indicating the interior ready condition of the printer. CONSTITUTION:A realtime monitor 13 is incorporated in a printer, and a task 11 for processing on ready condition display is provided among a number of processing tasks operated under control by the realtime monitor. The task 11 for processing on ready condition display is constructed so that it works at the lowest priority. While other tasks are not in running, namely the printer is under ready condition, the ready condition is displayed on a display unit 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer, in particular 1.
The present invention relates to a device that displays a ready state inside a printer that converts a print image according to a printing speed when it does not have an image memory for pages.

[0002]

2. Description of the Related Art Conventionally, in this type of printer, there is a display device which indicates that data is being received. This is to indicate that the data is being received, and it was not known whether the data required a lot of processing or was a data requiring less processing.

For this reason, in the conventional printer, if the received data is a data that requires a lot of processing even if it receives a small amount of data, the process of converting the received data will not meet the printing speed, resulting in a printing error. Nothing is displayed until this print error occurs, so it seemed to the printer user that a print error suddenly occurred even though the data was correct.

[0004]

In the conventional printer described above, there is no mechanism for displaying the internal state of the printer due to the nature of the received data, and it seems that a print error suddenly occurs even though the data is correct. .. Therefore, there is a drawback that the user of the printer has to repeatedly perform trials such as reducing the amount of data to bring out the capability of the printer.

The object of the present invention is to keep the above points in the printer in mind, and to provide a mechanism for informing the printer user of the internal processing state of the printer, and to prevent the printer user from generating a printing error. It is to make it possible to easily handle the combined and flexible actions.

[0006]

An internal ready status display device in a printer according to the present invention realizes a process of receiving data for printing from a host computer and converting the data for printing into a print image. In the printer, a real-time monitor that receives data and controls each process for converting the data into a print image,
It is configured to include a ready state display processing task that operates under the control of the real-time monitor, and a display device that displays the ready state passed from the ready state display task.

[0007]

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an internal ready status display device in a printer according to an embodiment of the present invention.

The internal ready status display device 1 in the printer of this embodiment is connected to the reception processing task 2, the decoding processing task 3 and the printing processing task 4, and the ready status display processing task 11 and the display device 12 are provided. The real-time monitor 13 is included.

The reception processing task 2 is for receiving the print data transmitted from the host computer 5 in the printer.

The decode processing task 3 is for decoding print data received in the printer and converting it into the internal data format of the printer.

The print processing task 4 is for converting the internal data converted into the internal data format of the printer into a print image according to the printing speed.

The real-time monitor 13 assigns CPUs by prioritizing the above-mentioned processing tasks. The print processing task 4, the decoding processing task 3, the reception processing task 2, and the ready status display processing task 11 are assigned in order of priority. When processing is completed even for a processing task with a high priority, the CPU is assigned to the processing task with the next priority. If there is no processing inside the printer, the ready status display processing task 11 is set to CPU
Is assigned. When the CPU is assigned from the real-time monitor 13, the ready status display processing task 11 gives a display instruction to the display device 12.

The display device 12 performs display in accordance with the display instruction passed from the ready status display processing task 11 and notifies the printer user of the internal ready status of the printer.

As described above, the ready display device in the printer displays the ready state on the display device when there is no processing inside the printer. The printer user can know the internal processing state of the printer by looking at the display state of the display device.

[0016]

As described above, according to the present invention, the processing status inside the printer can be displayed by providing the ready status display processing task, the display device and the real time monitor. This allows the printer user to flexibly respond to the internal state of the printer so as not to cause a printing error, and to maximize the performance of the printer without exceeding the processing limit of the printer. is there.
