Abstract

PURPOSE:To prevent the waste of the printing time and a form paper due to a failure in printing. CONSTITUTION:Printing data input are stored successively in a storage section 2 in order of inputs. The storage section 2 erases one part of printing data stored according to an indication from an operating section 14, or transfers printing data to a display section 3 and a printing section 5. The display section 3 displays printing data being transferred from the storage section 2 in the same type as the result of printing. The printing section 5 prints printing data being transferred from the storage section 2 on a form paper such as a document.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device, and more particularly to a printer device connected to a computer or the like.

0002

[Prior Art] Conventionally, in this type of printer device,
Unless the main unit is equipped with a print data confirmation function, such as some word processors, when printing on paper such as forms, the print result is known only after actually printing on the paper. Therefore, it was common for the printing results to not be as expected by the user.

[0003] With such conventional printer devices, the printing result is known only after actually printing on the paper.
This method has the disadvantage that printing time and paper are often wasted if the printing result is not as expected by the user.

0004

OBJECTS OF THE INVENTION The present invention has been made to eliminate the drawbacks of the conventional printers as described above, and an object of the present invention is to provide a printer device that can prevent printing time and waste of paper due to printing failures.

[0005]

SUMMARY OF THE INVENTION A printer device according to the present invention is a printer device that prints on paper, and includes storage means for storing print data on the paper, and displaying expected data of a print result generated from the print data. display means for displaying the predicted data on the display means, instruction means for instructing display of the predicted data on the display means, and control means for controlling display of the predicted data on the display means in accordance with instructions from the instruction means. It is characterized by

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, the printer device 1 includes a storage section 2 for storing print data, a display section 3 for displaying the print data stored in the storage section 2, an operation section 4 for instructing the operation of the printer device 1, and a storage section 3 for displaying the print data stored in the storage section 2. The printing unit 5 includes a printing unit 5 that prints the print data stored in the unit 2 on paper such as a form.

The storage unit 2 sequentially stores print data input from a host device (not shown) in the order of input. In addition, storage unit 2
erases part of the stored print data or transfers the print data to the display section 3 or the printing section 5 in accordance with instructions from the operation section 4. The print data transferred from the storage section 2 to the display section 3 is displayed in the same format as the print result, and the print data transferred from the storage section 2 to the printing section 5 is printed on actual paper such as a form.

The operation section 4 instructs the storage section 2 to perform a printing operation designated in advance from the outside by the operator, or to change the printing operation during printing. Based on the instructions from this operation section 4,
Erasing part of the print data stored in the storage unit 2, displaying the print data on the display unit 3, or displaying the print data on the print unit 5
Printing is executed. The storage and transfer of the print data in the storage section 2, the conversion and display of the print data in the same format as the print result in the display section 3, and the printing of the print data in the print section 5 are each performed by a control section (not shown). controlled.

The operation of one embodiment of the present invention will be explained using FIG. 1. Print data input from a host device such as an external computer is stored in the storage unit 2 in the order of input. At this time, the storage section 2 performs operations based on instructions from the operation section 4. That is, the storage unit 2 can immediately transfer the stored print data to the display unit 3 or the printing unit 5, or can transfer the stored print data to the operation unit 4 once all the print data has been stored.
The print data is transferred to the display section 3 or to both the display section 3 and the print section 5 in accordance with instructions from the display section 3 .

[0011] When the print data stored in the storage unit 2 is immediately transferred to the display unit 3 or the printing unit 5, the display unit 3 displays print data that is ahead of the print data to be transferred to the printing unit 5 by a predetermined amount. is transferred. Therefore, it is possible to print the print data on the printing section 5 while checking how the print result will be printed by looking at the predicted printing result on the display section 3. At this time, the printing data transferred from the storage section 2 to the printing section 5 is controlled by giving instructions from the operation section 4, and printing can be stopped at any position or unnecessary parts of the printing data can be skipped. It can be printed.

On the other hand, when transferring the print data to the display section 3 or both the display section 3 and the printing section 5 according to instructions from the operation section 4 after all the print data has been stored, the instruction is given from the operation section 4. By doing so, the entire print data can be transferred to the display section 3 and checked. Further, by giving an instruction from the operation section 4, the print data transferred from the storage section 2 to the printing section 5 can be controlled, and only arbitrary parts of the print data can be printed in an arbitrary order.

FIG. 2 is a diagram showing a method of erasing print data stored in the storage section 2 of FIG. 1. In FIG. 2(a), documents ■-1 to document ■-4 are stored as print data in the storage unit 2.
This shows a case where document ■ consisting of is stored, and when document ■ consisting of document ■-1 to document ■-4 is input as the next print data, document ■ is automatically deleted.

In FIG. 2(b), at the time when an instruction is given from the operation unit 4, the document ■ consisting of documents ■-1 to document ■-4 stored as print data in the storage unit 2 is all erased. This shows the case where

In FIG. 2(c), any part of the document ■ consisting of documents ■-1 to document ■-4 stored as print data in the storage unit 2 (in the figure, document ■-3
, document ■-4) are deleted, and immediately after that, document ■ consisting of documents ■-1 to document ■-3 is added as the next print data.

In this way, by transferring the print data stored in the storage section 2 to the display section 3 according to instructions from the operation section 4 and displaying it in the same format as the print result, the printing section 5 can You can check the print result of the print data before printing. Therefore, it is possible to prevent printing time and waste of paper due to printing failures, and it is possible to efficiently print on paper such as forms.

[0017]

As explained above, according to the present invention, the print data to be printed on paper is temporarily stored in the storage unit, and the expected print result data generated from this print data can be generated by an external instruction. By displaying the information according to the following, it is possible to prevent printing time and paper wastage due to printing failures.
