Abstract

PURPOSE:To shorten the time required for starting of the printer loading print control programs from an external storage reading device. CONSTITUTION:At the time of applying power or depressing a reset switch 6, a processor 2 reads the specification condition of a selection switch 7. At the time of diagnostic specification, the processor 2 diagnoses an internal storage device 4 and loads the print control programs from a storage medium 31 to the internal storage device. At the time of specifying the program load, the only program loading is performed. At the time of specifying the program execution, no program loading is performed. Then the processor 2 controls wholly the printing of the device according to the program in the internal storage device 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus, and more particularly to a printing apparatus capable of loading a program for printing control from an external storage reading device.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional printing device of this type includes an input device 1, a processor 2, an external storage reading device 3, an internal storage device 4, an output device 5, and a reset switch. 6 and. A storage medium 31 such as a flexible disk stores a program for controlling the printing operation of the printing device.

The processor 2 controls the entire printing apparatus, diagnoses the normality of the internal storage device 4 when the power is turned on or when the reset switch 6 resets (starts up), and then the external storage reading device 3 is activated. A program is loaded from the storage medium 31 to the internal storage device 4 via the program, and control is transferred to the program to enable printing. After that, the print data sent from the host device is input to the input device 1
Is input and is edited by the processor 2 to complete one page of output data, and the output device 5 is used to execute a one-page printing operation.

[0004]

In this conventional printing apparatus, the internal storage device is always diagnosed and the program is loaded from the external storage device when the power is turned on or the reset operation is performed. Such a process is always performed during the debugging work in which the reset operation is repeatedly performed by the reset switch, so that the work efficiency is deteriorated.

[0005]

The printing apparatus of the present invention is
Input device for inputting print data from the storage device and storage medium
Read programs stored in the body to control printing operations
An external storage reading device and the read program are stored.
Internal storage device and output device that prints out print data
And start-up by turning on or resetting the printing device
Select switch to select and specify the processing at the time of rising,
Read the designated state of the selection switch according to this designation
Normality diagnosis for the internal storage device and the external storage
Of each process of loading the program via the storage device
Execution / non-execution is determined and stored in the internal storage device.
Printing input to the input device according to the program
Control device for editing data and printing out from the output device
It is equipped with

In the above structure, the external storage reading device may include the storage medium storing a program for controlling the printing operation.

[0007]

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

FIG. 1 is a block diagram of an embodiment of the present invention. In the drawing, the printing device includes an input device 1 for inputting print data from a higher-level device, a control device (processor) 2 for controlling the whole, an external storage reading device 3 for reading a print control program from a storage medium 31, An internal storage device 4 for storing the print control program, an output device 5 for printing out, a reset switch 6 for instructing the processor 2 to reset, and a selection switch 7 for selectively instructing the processor 2 at the time of start-up. I have it. Storage medium 3
1 normally uses a flexible disk, but an IC card can also be used. The external storage reading device 3 has a configuration and structure suitable for the type of the storage medium 31.

FIG. 2 is a diagram showing the operation transition from the power-on to the printable state in this embodiment. The operation will be described with reference to FIG.

When the reset operation is started when the power is turned on (step 100) or the reset switch 6 is pressed (step 101), the processor 2 reads the designated state of the selection switch 7 (step 102).

If the selection switch 7 is in the diagnosis-specified state A, the processor 2 diagnoses the normality of the internal storage device 4 (step 103), and the print control program is sent from the storage medium 31 via the external storage reading device 3. After loading (step 104), this program is executed to shift to the printable state (step 105).

If the selection switch 7 is in the program load designation state B, the processor 2 only loads the program from the storage medium 31 (step 104) and becomes the printable state (step 105).

When the selection switch 7 is in the program execution designation state C, control is transferred to the print control program already loaded when the reset switch 6 is pressed, and the printing is ready (step 105).

In the printable state, the print data sent from the host device is processed by the input device 1 and edited by the processor 2. The drawing data for one page is completed, and the printing operation for one page is executed using the output device 5.

In this way, the switch 7 for selecting whether to execute the diagnostic process of the internal storage device 4 at the start-up and the program loading process from the external storage device 3 is executed.
By selecting with, the startup time of the printing device in the reset operation can be shortened if the internal storage device 4 is normal or the program is loaded into the internal storage device 4 from the external storage device 3. Is.

[0016]

As is apparent from the above description, according to the printing apparatus of the present invention, each processing of normality diagnosis processing of the internal storage device at startup and loading of the print operation control program from the storage medium is performed. You can select execution or non-execution of
By not executing each process at startup, the startup time of the device can be shortened.
