Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer, and more particularly to a multifunction printer having a copying function and a facsimile communication function, such as a digital printer.

[0002]

2. Description of the Related Art Recently, with the development and sophistication of digital technology in signal processing, a printing apparatus having a copying function and a facsimile communication function has come into the market. This printing device has a copy function of 30 sheets / min.
In addition to realizing high-speed, high-quality printing of 400 dpi,
In addition to normal copying functions, various image processing functions such as black and white reversal, shading, and shadowing, gradation functions, graph functions to create graphs from handwritten numbers, trace functions to trace handwritten straight lines, light from paper media It has a function of copying to a heterogeneous medium such as a magnetic disk, and has a printing function such as an offline printer function for printing data of a personal computer or word processor via a floppy disk and an online printer function of a predetermined personal computer. Further, it has a facsimile communication function via a communication line network such as a public telephone network. In addition, by having such a copying function, a printing function, and a facsimile communication function in one machine, there is an advantage that it does not occupy a space as compared with a stand-alone machine for each function, and one printing machine can perform printing work. Since it is possible to aggregate daily tasks such as exchanging image information by facsimile communication with other locations, there is an advantage that daily tasks can be performed efficiently.

[0003]

However, in such a conventional printing apparatus having a facsimile communication function, even if image information for a plurality of pages is received, one page of image information for one page is received. Since there was only a function to print each side of the recording paper, the printing function of the printing device is a double-sided printing function that prints one side on each side of the recording paper, and a page that prints two pages of image information on one side of the recording paper. Continuous shooting function,
Despite the fact that one side of the recording paper has a backside printing function that prints on the other side of the recording paper that has already been printed, the image information data received by facsimile communication using those printing functions I could not print and eject. That is, even though it has a high-performance printing function such as a double-sided printing function and a page continuous shooting function, the image information data received by facsimile communication can only be printed on one side on the recording paper, and the recording paper is wasted. There's a problem.

Therefore, according to the first aspect of the invention, when the data size of the received image information is a plurality of pages,
By setting the printing function to print on both sides of the recording paper one by one, it is possible to reduce the printing cost by effectively using the recording paper without wasting the recording paper. An object of the present invention is to provide a printing apparatus that can contribute to integration.

Further, depending on the content of the image information transmitted from the transmission source terminal and the convenience of the user of the self-printing apparatus,
When the number of pages corresponding to the image information received by the receiving unit is a plurality of pages, it may be desired to print the received page image information for two pages on one side of the recording paper. Therefore, according to the second aspect of the invention, when the received image information has a data size of a plurality of pages, the print function is set to print conditions such that two pages of the image information are printed on one side of the recording paper. An object of the present invention is to provide a printing apparatus that can save paper and reduce printing cost, and that can compress information on one side of recording paper to contribute to the integration of information. And

In daily operations, it is preferable that the back side of a paper that has been used once can be reused as a recording paper because the recording paper can be saved. However, if the printing condition of the printing unit is set to print on both sides of the recording paper, one side of the recording paper stored in the recording paper tray is already printed. , If you print one side on each side of the recording paper, the image information received via the communication network will be printed on one side of the recording paper that has already been printed at least once, and the image information for that page will be lost. There is a problem that it cannot be restored as meaningful image information.

Therefore, according to the third aspect of the present invention, when the back side of the recording paper whose one side has already been printed is used as the recording surface as the recording paper, the printing conditions are set so that one side is automatically printed on each side of the recording paper. An object of the present invention is to provide a printing apparatus capable of effectively utilizing paper resources and preventing loss of received image information by switching to printing conditions for printing on only one side of recording paper.

In everyday business, it may be more convenient to print two pages each on one side of the recording paper which has already been printed on one side. Considering the consumption cost of the recording paper, printing cost can be reduced if two pages can be printed on each side. Therefore, in the invention described in claim 4, when the back surface of the recording paper on which one side is already printed is used as the recording surface,
By automatically switching the printing conditions such that the page image information received on the other side of the recording paper is printed every two pages, it is possible to effectively use the recording paper and prevent the loss of the received image information. An object of the present invention is to provide a printing device that can perform printing.

Further, under the printing condition that one side is printed on each side of the recording paper, when the number of pages corresponding to the image information received by the receiving means is an odd number of pages, both sides of the normal recording paper are processed from the beginning to the end. I printed one side each on the
The back side of the recording paper on which the page corresponding to the last page of image information is printed is printed even if there is no image information, and the printing time becomes long by that much, and the user's business time is wasted. Is not preferable.

Therefore, according to the invention of claim 5, when the number of pages corresponding to the received image information is an odd number of pages,
The image information corresponding to the last page of the received image information is printed on one side of the recording paper, and then the other side of the recording paper on which the image information corresponding to the last page is printed is ejected without printing. An object of the present invention is to provide a printing apparatus that contributes to improving the work efficiency of users by shortening the printing time for printing image information on paper.

When the image information for the received page is printed on two sides of one side of the recording paper, when the number of pages corresponding to the received image information is an odd number of pages, the final image information of the received image information is printed. A blank space is generated on a page of the recording paper on which image information corresponding to the page is recorded. It is preferable to discharge the margin portion without printing it because the printing time and the printing material are saved.

Therefore, according to the invention of claim 6, when the number of pages corresponding to the received image information is an odd number of pages, the image information corresponding to the last page of the image information is printed on a predetermined area of the recording paper. However, it is an object of the present invention to provide a printing apparatus that contributes to the improvement of work efficiency by shortening the printing time by not printing in a region other than a predetermined area. In addition, if the model that can temporarily store the image information data received by facsimile communication and can print the image information received with the printing function of the device by the printing function specified by the user is received. Since it is not possible for the user to know when the image information is printed and discharged, it is not possible to switch the printing function at the time of printing the facsimile reception data. In normal business, when image information is received via the communication network when the printing device is used as a copier, the printing conditions when the printing device is used as a copier remain unchanged. When the received image information is printed, there is a possibility that a printed image that does not appeal to the user is formed.

Therefore, in the invention described in claim 7, when the image information is received via the communication line network, the image information is printed by switching to the printing conditions according to claims 1 to 6, and the image information is printed. It is an object of the present invention to provide a printing apparatus capable of printing image information under the printing conditions desired by the user by switching to the printing conditions before the printing of the image information after completion of the process, without the intervention of the user.

According to the sixth aspect of the invention, since the odd page determination means is provided, it is possible to determine whether or not the number of pages corresponding to the image information received by the reception means is an odd page, and the determination is made. The printing function of the printing means can be controlled based on the result. Then, when the number of pages corresponding to the image information is an odd number of pages, printing is performed under the print condition that two pages of the image information are printed on one side of the recording paper except for the page corresponding to the last page of the image information. The printing of the page corresponding to the final page of the image information is performed on a predetermined area on one surface of the recording paper, and is not printed on a portion other than the predetermined area on the one surface of the recording paper and the other surface. Therefore,
The printing time for printing the image information on the recording paper can be shortened as compared with the conventional case, which can contribute to the improvement of the work efficiency of the user.

According to the invention described in claim 7, when the image information is received through the communication network, the image information is printed by switching to the printing conditions according to claims 1 to 6, and the printing of the image information is completed. Since the printing condition is changed to the printing condition before the printing of the image information, it is possible to print the image information under the printing condition desired by the user without the intervention of the user.
