[0015]
The operation when printing a document or report received by the facsimile apparatus 1 will be described with reference to the flowchart of FIG.
[0016]
When printing the received document or report, the system control unit 22 determines whether to print the received document (step S1). As a result of the determination, when the received document is not printed, it is determined whether or not the report is printed (step S2). When the report is printed, the text part of the report is read from the character generator of the read-only memory 24. The image information is expanded to the page memory of the system memory 23. Further, the image portion of the report is read from the image memory 28, decoded by the encoding / decoding portion 29, and expanded in the page memory of the system memory 23. When the image data of the text part and the image part of the report are developed in the system memory 23, the system control unit 22 sends a report print command to the engine control unit 30, and sends the image data developed in the system memory 23 to the engine control unit 30. . When a report print command is sent, the engine control unit 30 determines whether double-sided printing or single-sided printing image is set as a report printing method in the duplex / single-sided switching control unit 31 (step S3). If printing is set, the single-sided printing function is selected and the image forming unit 2 executes printing (step S4). When printing a report by this single-sided printing, the engine control unit 30 forms a page break for the text portion and the image portion to be printed, and prints the text portion and the image portion on different recording sheets (step S5). If double-sided printing is set, the double-sided printing function is selected and printing is executed by the image forming unit 2 (step S6). When printing a report by this double-sided printing , the engine control unit 30 forms a page break for the text portion and image portion to be printed, prints the text portion on the surface of the recording paper, and prints the image portion on the recording paper on which the text portion is printed. Printing on the back side (step S7). When printing the text part and the image part of this report, if there are three pages of text parts, for example, the first and second pages of the text part are printed on the front and back of the first sheet of recording paper. 3 pages of the text portion are printed on the front surface of the recording paper, and the image portion is printed on the back surface of the second recording paper.
[0017]
Thus, when printing a report, the text part and the image part are printed with a page break, so that an easy-to-read report can be printed.
[0018]
When printing the received document, the system control unit 22 reads the image data of the received document from the image memory 28, decodes it by the encoding / decoding unit 29, and sequentially develops it in the page memory of the system memory 23. When the image data for one page is developed in the system memory 23, the system control unit 22 sends a print command for the received document to the engine control unit 30, and sends the image data developed in the system memory 23 to the engine control unit 30. When the received document print command is sent, the engine control unit 30 determines whether double-sided printing or single-sided printing image is set as the received document printing method in the duplex / single-sided switching control unit 31 (step S8). If double-sided printing is set, the double-sided printing function is selected to cause the image forming unit 2 to execute printing (steps S9 and S10). If single-sided printing is set, the single-sided printing function is selected and printing is executed by the image forming unit 2 (steps S11 and S10).
