Abstract

PURPOSE:To communicate PDL data as they are to be used for printers. CONSTITUTION:A communication procedure incorporating means 12 incorporates PDL data prepared by a PDL data preparing means 11 on the transmission side, for example, the communication procedure of a personal computer communication or facsimile equipment, which are sent through a communication line to the other party by a transmission means 13. At the side of reception, data are received by a reception means 14 connected to the communication line, which are supplied to a PDL data extracting means 15 so as to be extracted with PDL data. In this case, the edition is enabled while performing the rotation processing or the variable power processing on the PDL data as need. The PDL data is analyzed by a PDL data analysis means 16 and supplied to a printer 17. Thus, the same PDL data or edited PDL data as the data received by the printer 17 are printed out. In This communication equipment, PDL data are transmitted and received as they are, resulting in facilitating the edition at the reception side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device used for a printer or the like and capable of transmitting and receiving PDL data.

[0002]

BACKGROUND OF THE INVENTION When printing data created by a personal computer or the like with a printer, the data is converted into PDL (Page Description Language) data used by the printer and then supplied to the printer to print out. It is supposed to be done. Since the PDL data is vector information, for example, it is easy to rotate or scale the graphic data, and it is also easy to edit the created data.

On the other hand, when sending data created by a personal computer to a remote place, the data created by the personal computer 1 is converted into PDL data as shown in FIG. To fax machine 3A
Or by connecting a FAX adapter 4 or a FAX board to the personal computer 1 as shown in FIG. 1B and converting the PDL data into MH code, MR code, MMR code, etc. used in the facsimile machine. It is usually sent. In the above two transmission methods, the receiving side receives the data by the facsimile device 3B or the like.

[0004]

As described above, the method of temporarily printing out the data created by the personal computer 1 and transmitting / receiving the data by the facsimile device 3 has a problem that the image quality of the data is deteriorated. Further, in the method of converting the PDL data into a code used in the facsimile apparatus and transmitting / receiving the code, the code conversion causes the data to be different from the original data. For example, it becomes difficult for the receiving side to perform scaling processing. There's a problem. In other words, in this method PD
The features of L data will not be utilized.

Therefore, the present invention solves the above-mentioned problems and proposes a communication device capable of performing communication by utilizing the characteristics of PDL data.

[0006]

In order to solve the above problems, according to the present invention, the transmitting side includes PDL data creating means, communication procedure incorporating means for incorporating the PDL data into a predetermined communication procedure, and communication procedure. PDL data extracting means for transmitting PDL data based on the communication procedure on the receiving side, receiving means for receiving data including PDL data based on the communication procedure, and PDL data extracting means for extracting PDL data from the received data. PD to analyze
It is characterized in that it is provided with L data analysis means.

[0007]

In FIG. 1, the PDL data created by the PDL data creating means 11 on the transmitting side is incorporated into the communication procedure of the personal computer communication or the facsimile machine by the communication procedure incorporating means 12, for example. Then, the transmission means 13 transmits the data to the other party via the communication line.

On the receiving side, the data is received by the receiving means 14 connected to the communication line and is supplied to the PDL data extracting means 15 to extract the PDL data. At this time, if necessary, the PDL data can be edited in various ways such as rotation processing and scaling processing. This PDL data is analyzed by the PDL data analysis means 16 and supplied to the printing means 17. As a result, the same PDL data as received or the edited PDL data is printed out.

[0009]

Next, an embodiment of a communication device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows functional blocks of a communication device according to the present invention. In the figure, 11 is a PDL data creating means for creating PDL data, and a personal computer or the like is used. Reference numeral 12 is a communication procedure incorporating means for incorporating PDL data into a personal computer communication or a communication procedure of a facsimile machine. Reference numeral 13 is a transmission means, which is connected to the communication line and transmits the PDL data incorporated in the communication procedure.

Reference numeral 14 is a receiving means, which is connected to a communication line and receives the information transmitted from the transmitting means 13. 15
Is a PDL data extraction means, and the PD can be extracted from the received information.
Extract L data. Reference numeral 16 is a PDL data analysis means, which analyzes the PDL data and supplies it to the printing means 17. As a result, the received data is printed out.

FIG. 2 shows the configuration of a communication device to which the present invention is applied. In the communication device shown in FIG. 9A, PDL data created by the sending personal computer 1A is incorporated into the personal computer communication procedure and transmitted from the communication line. On the receiving side, the personal computer 1B connected to the communication line receives the data including the PDL data, extracts the PDL data from the data, analyzes the PDL data, and supplies the data to the printer 2 to print out the received data. In this communication device,
Since the PDL data created on the sending side is received as it is on the receiving side, there is no deterioration in image quality when printed out, and it is possible to edit on the personal computer 1B before printing out on the receiving side. ..

In the communication device shown in FIG. 2B, the PDL data created by the sending personal computer 1A is MF.
It is supplied to the device 5A (having a multi function, for example, a printer function and a facsimile function). This MF device 5
At A, the PDL data is incorporated into the communication procedure of the facsimile machine, and this is transmitted to the other party via the communication line.

On the receiving side, the MF device 5B connected to the communication line receives the PDL data, analyzes it, and supplies it to the printer section to print it out. In this communication device, the PDL data is not converted into image information but directly incorporated into the communication procedure of the facsimile device for transmission / reception, so that the original data is not deteriorated. Therefore, it becomes easy for the receiving side to perform various editing processes such as rotation and scaling.

[0015]

As described above, according to the present invention,
The transmitting side is provided with a PDL data creating means, a communication procedure incorporating means for incorporating the PDL data into a predetermined communication procedure, and a transmitting means for transmitting the PDL data based on the communication procedure, and the receiving side is based on the communication procedure.
