Abstract

PURPOSE:To conduct a printing processing corresponding to a changed paper size even with the occurrence of a change in paper size, by enlarging/contracting an image stored in a print image storage means on the basis of a signal from an input means, and printing out the enlarged/contracted image. CONSTITUTION:Document data is read out of a magnetic disk device 9, stored once in a document data buffer 2, a converted to a bit image by a bit image forming mechanism 4, and stored in a bit image buffer memory 3. The bit image is outputted to a printing execution part 6 and therein a printing processing is conducted. When the size of a printing paper in use is to be changed, an operator inputs a signal according to a changed size to a bit image enlarging/contracting mechanism 5 using a keyboard 8. On the basis of the inputted signal, the enlarging/contracting mechanism 5 executes an enlarging/ contracting processing according to the changed printing paper size to the bit image stored in the bit image buffer memory 3. Then, the enlarged/ contracted bit image data is outputted to a printing execution part 6 to be printed on the changed printing paper.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a printer suitable for printing out document data created by, for example, a word processor.

(Prior Art) Conventionally, when printing out a document created by a word processor, for example, it is necessary to set a document format that matches the set paper size when editing the document.

However, in this method of setting the document format in advance and printing out the created document, it is operationally difficult to change the paper size during printing and print according to the changed paper size.

(Problems to be Solved by the Invention) The present invention is intended to solve the above-mentioned problems with conventional printers. Even if the paper size is changed during the printing process, it is possible to easily print the paper size after the change. The purpose of the present invention is to provide a printer that can print images according to their size.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above-mentioned object, the printer of the present invention includes a print image storage means for storing an image to be printed, and a signal corresponding to a change in size of printing paper. an image enlargement/reduction means for enlarging/reducing the image stored in the print image storage means based on a signal from the input means; and a printout means for printing out the enlarged/reduced image. It is equipped with the following.

(Function) In the printer of the present invention, the image enlargement/reduction means enlarges/reduces the image stored in the print image storage means based on the signal from the input means, so that the paper size cannot be changed during the printing process. Even if this occurs, it is possible to print an image according to the changed paper size with a simple operation.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing the configuration of a document creation device equipped with a printer according to an embodiment of the present invention.

In the figure, 1 is a document editing mechanism that has the function of editing the document data to be created and also controls all the mechanical parts in this device, and 2 is a document that temporarily holds the document data to be printed out. data buffer, 3
4 is a bit image buffer memory that stores document data converted into a bit image, and 4 is a bit image conversion mechanism that converts the document data held in the document data buffer 2 into a bit image and develops it on the pit image buffer memory 3 described above. It is.

Further, 5 is a bit image enlargement/reduction mechanism 6 for enlarging/reducing the bit image stored in the bit image buffer memory 3 to a size corresponding to an arbitrary paper size such as A4, BS, etc. according to an instruction from an operator.
is a print execution section that performs actual printing operations based on the image data stored in the bit image buffer memory 3.

Further, 7 is a display unit such as a CRT for displaying the bit image stored in the bit image buffer memory 3; 8 is a keyboard for inputting character codes and instructions necessary to control this device; 9; is a magnetic disk device for storing created document data.

Next, the printout operation in the document creation apparatus of this embodiment will be explained with reference to the flowchart shown in FIG.

First, by inputting using the keyboard 8, specify the document data to be printed out from among the document data created and edited by this document creation device, and then specify the size of the printing paper currently set in the main body of the print execution unit 6. Set the document format and print format according to the

The specified document data is read from the magnetic disk device 9 (step a) and temporarily stored in the document data buffer 2 (step b).

Next, the document data stored in the document data buffer 2 is converted into a bit image by the bit image conversion mechanism 4 and stored in the bit image buffer memory 3 (step C).

Thereafter, the bit image stored in the bit image buffer memory 3 is output to the print execution section 6, whereby actual printing processing is performed.

Here, if it is necessary to change the size of the printing paper used, the operator uses the keyboard 8 to input a signal corresponding to the changed size to the bit image enlargement/reduction mechanism 5 (step d).

Thereby, the bit image enlargement/reduction mechanism 5 executes enlargement/reduction processing according to the changed printing paper size on the bit image stored in the bit image buffer memory 3 based on the input signal (step e ).

Thereafter, the enlarged/reduced bit image data is output to the print execution unit 6, and thereby printing processing on the changed printing paper is performed (step f).

Thus, according to the document creation device equipped with the printer of this embodiment, the data in the bit image buffer memory 3 can be changed by the operator inputting a signal corresponding to the change size to the bit image enlargement/reduction mechanism 5 using the keyboard 8. It is possible to enlarge/reduce the size of the print paper and execute the printing process in accordance with the size-changed print paper, so even if the print paper size changes during the print process, it can be flexibly handled.

[Effects of the Invention] As explained above, according to the printer of the present invention, even if the paper size is changed during the printing process, it is possible to print an image according to the changed paper size with a simple operation. It can be carried out.
