BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention converts edited image information into a page description language and transfers the converted PDL data to each other between facsimile communication apparatuses connected via a public line. The present invention relates to a facsimile device for outputting and a page description language transfer processing method of the facsimile device.

2. Description of the Related Art Conventionally, a composite process in which page manuscripts or image information created by a computer or the like is transmitted by facsimile communication processing through a public line such as a telephone line and the transmitted image information can be output to a recording medium. A device has been proposed.

In this case, in facsimile communication, an image is read, converted into an electric signal, coded, and then placed on a public line. In addition, a document or the like created by a computer or a word processor is once image-formed and output by a printer or is expanded on a memory and then encoded.

When data of a document created by a computer or the like is output, the data to be sent to the printer is often a well-known page description language (hereinafter referred to as PDL) such as LIPS (product name) or Postscript (product name). It is used.

However, if the image output by the PDL is transferred by the facsimile, the image quality is considerably deteriorated. This is because when outputting from a printer in PDL, the resolution is 300 DPI or 400 DPI, whereas the facsimile standard is 8pe1 / 3.85.
It is a book (about 200 DPI). Therefore, the resolution must be reduced considerably.

Further, the amount of data coded after expanding the amount of PDL data increases considerably. Therefore, the PDL data has been purposely converted into data having a low resolution and requiring a long communication time and cost before being transmitted.

I was trying again. If such data is transmitted, the operator cannot see the status of the printer, and cannot determine whether all the image information based on the PDL data transferred from the receiving printer has been normally output.

Next, the PD from the computer of this embodiment
A case where the facsimile unit 4 transmits and receives L data (print data) will be described.

The PDL data from the computer, for example the LIPS data, is transferred to the S of the computer interface unit 7.
The core unit 10 is reached via the CSI interface 704. And since the data goes to the facsimile section 4,
The data is transferred to the dual port memory 410 of the facsimile unit 4.

Further, prior to the data, the facsimile unit 4
Is set to the data transmission by the SCSI command and the telephone number of the other party is set. Then, the facsimile unit 4 starts a facsimile call.

FIG. 8 is a diagram showing an example of a communication protocol at the time of a facsimile call in the facsimile apparatus according to the present invention. For example, a facsimile call procedure (protocol) according to CCITT recommendation T30 is shown.

The procedure of data transmission / reception will be described below with reference to FIG.

When the calling side dials and the called side connects the line, the procedure of FIG. 8 is started.

First, in phase A, the called side issues CED.

Subsequently, the phase shifts to phase B, and control signals NSF, CSI, DIS according to CCITT recommendation T30 are issued. Here, in the fourth octet of the facsimile information field (FIF) of the control signal NSF, the information necessary for the operation of this embodiment is assigned.

FIG. 9 is a diagram for explaining the structure of the control signal transmitted from the facsimile section 4 shown in FIG.

As shown in this figure, the first and second octets are CCITT member codes, and the third octet is a manufacturer code. Then, a PDL that can be used for bits 0, 1 and 4 of the fourth octet, for example, LIP
Assign the presence or absence of S, PS, PCL deployment capabilities. If the bits 0, 1 and 4 of the fourth octet are "1", it is determined that the capability is available.

The CPU 412 on the calling side stores the capability of the other party in the backup memory 417. Further, the fifth octet (not shown) is allocated as an area to the current operation mode of the formatter unit 8, for example, a mode in which the LIPS or the PR201 emulation mode is set.

Then, the calling side sends control signals NSS and TS.
Issue I and DCS. Here, the operation mode and PDL are designated. For example, if it is LIPS, the control signal NS
Bit 0 of the 4th octet of S is set to "1" (see FIG. 9).

Here, if the transmission side is set so as not to transmit if the other party is emulation mode, the control signal DCN is sent to disconnect the line and output an error report.

On the other hand, if transmission is possible, training is conducted to check the line condition.
Train at 4 Kbps. Then, if it is in a good state, it shifts to phase C, and if not, the baud rate is reduced in the order of 9.600 bps to 4.800 bps.

Then, the telephone number of the other party and the state of the line corresponding to the telephone number are stored in the backup memory 417.

As the LIPS data, the data in the dual port memory 410 is temporarily stored in the memories 405-4.
08 (memory A to D) to a free area, and then transfers to the line via MODEM 414 and NCU 415.

When all the image signals or PDL data are transmitted from the calling side, the procedure moves to phase D. When the calling side outputs the control signal EOP to indicate the end, the called side outputs the control signal MCF. Then, the phase E is entered, and the control signal D
The line is closed by the CN and the facsimile call (facsimile communication) ends.

The page description language processing method of the facsimile apparatus according to the present invention will be described below with reference to the flowchart shown in FIG.

FIG. 10 is a flow chart showing an embodiment of the page description language processing method of the facsimile apparatus according to the present invention. Note that (1) to (10) indicate each step.

In step (1), the facsimile section 4 performs the above-mentioned receiving operation. Next, in step (2), the received data is transferred from the facsimile unit 4 to the formatter unit 8 via the core unit 10. For example, the facsimile section 4 on the transmitting side
Even if 1 Mbytes of data is transferred between the receiver and the facsimile unit 4 on the receiving side, the formatter unit 8 transfers several Kbytes at a time here. Then, in step (3), the transferred image of several K bytes is developed.

In step (4), the formatter unit 8 determines whether or not there is a paper discharge command, and in step (5), if there is a paper discharge command, the image is output to the printer unit 2. Then, in step (6), the formatter unit 8 returns to step (2) to transfer the data if the facsimile unit 4 still has data, and repeats the expansion. The operation ends when all the data is processed.

On the other hand, if there is no paper discharge command in step (4), the process proceeds to step (7), the next data is transferred and repeated, but even if all the data received by the facsimile unit 4 has been processed. If the last developed page ends without a paper discharge command, it is determined that there is an error in the data, and the process proceeds to step (8).

In a normal printer, the data may be sent again from the host computer even after all the data has been developed, so an error does not occur immediately.

However, in the case of this embodiment using the facsimile unit 4, the data is complete and does not continue. Therefore, the fact that there is no paper discharge command at the end means that the data is in error.

Further, in the step (4), an error check may be performed together with the paper discharge command check. For example, if the memory overflows in the printer, an error occurs and no further processing is performed. When such an error has occurred a predetermined number of times in advance and it is detected, the process goes to step (8).

At step (8), as the error processing, the unprocessed data in the facsimile section 4 and the formatter section 8 is cleared. In step (9), the occurrence of a gull is displayed on the operation display unit, and in step (10), the same reception result error report as a normal facsimile outputs is output. This may be done by either the facsimile section 4 or the formatter section 8.

As another error detecting means, first, the transmitting side performs a checksum or CRC check before transferring the data from the core unit 10 to the facsimile unit 4, and adds the result to the beginning of the data.

On the receiving side, all the data received by the facsimile section 4 is transferred to the core section 10. The core section 10 checks the same rule as the transmitting side except for the leading data and sets it as the leading data.

As a result, the check is completed before the formatter unit 8 develops, so that quick response can be taken.

Correspondence and operation between the present embodiment and the seventh to tenth inventions will be described below.
