Normally, the paper ejection port selection lever 205 is set to eject paper to the paper ejection port 202. The paper ejection port selection lever 205 is used by the print recording control unit 1
The pulse motor 204 can be operated by driving the pulse motor 204 in accordance with the paper discharge port selection signal given from 01.
The operation of the print recording device having such a configuration will be described below.

FIG. 3 is a flow chart showing a control flow of the print recording apparatus of the present invention. As shown in the figure, after the start of printing, the print success / failure detection unit 103 detects the print success / failure of the page currently being printed.
As described in Japanese Patent Application Laid-Open No. 9-6231, the success or failure of printing is judged by the ink ejection failure detecting means. When one page has been printed without a misprint being detected, the sheet is discharged to the sheet discharge port 202, and if there is a next page, the next printing is started. When the misprint is detected by the print detection means, the printer stops printing and returns a misprint error signal to the host computer via the bidirectional interface. Then, the pulse motor 204 is driven by the paper ejection port selection signal for selecting the paper ejection port, and the paper ejection port 2
The paper ejection port selection lever 205 is rotated so that the paper is ejected to 03. The misprinted paper is discharged to the paper discharge port 203. After the paper ejection is completed, the pulse motor is driven in the opposite direction to the above-mentioned case by the paper ejection port selection signal to select the paper ejection port 202. The printer recovers the cause of the misprint if it can be recovered by the printer itself, and displays an error if it cannot recover. After recovery, reprint the misprinted page.

Regarding the sequence for reprinting, for example, when the host computer transfers data to the printer, the data is once stored in the printer spooler and then transferred to the printer. Data is stored in the printer spooler until printing of one page is completed, and if printing is stopped midway, the data is transferred again to the printer side. Such control can be easily realized by the printer driver.

(Second Embodiment) In the first embodiment, when misprinting is performed, the misprinted page is discharged to another discharge port selected by the discharge port automatic switching means. It was a thing.

However, in this embodiment, as shown in FIG. 6, the paper feed rollers 601 and 602 are separated into two. Normally, the paper feed rollers 601 and 602 are rotated at the same speed by the drive system 603.
This makes it possible to rotate the paper feed rollers 601 and 602 at different speeds. The operation of the print recording apparatus having such a configuration will be described below.

FIG. 7 is a flowchart showing the control flow of this embodiment. As shown in the figure, after the start of printing, the print success / failure of the page currently being printed is determined by the print success / failure detection means. Printing is started on one page without detecting a misprint. When the misprint is detected by the print success / failure detection means, the printer stops printing and returns a misprint error signal to the host computer via the bidirectional interface. When ejecting the misprinted paper, the transmission control means operates the transmission 604 to eject the paper while rotating the paper feed rollers 601 and 602 at mutually different speeds. As a result, the misprinted paper is ejected in a form shifted from the normal ejection. Therefore, since the paper is discharged to the paper discharge tray 407 in an abnormal state, it is possible to easily determine whether the paper is normally printed or misprinted paper. In addition, Japanese Patent Fair 2-
As described in Japanese Patent Publication No. 95880, a further effect can be obtained by a technique of detecting a misprint and printing an error mark on the misprint paper before discharging.
After the paper is discharged, the transmission control means operates the transmission 604 to make the rotation speeds of the paper feed rollers 601 and 602 equal to each other as usual. The printer recovers the cause of the misprint if it can be recovered by the printer itself, and displays an error if it cannot recover.
After recovery, reprint the misprinted page. Regarding the sequence for reprinting, for example,
When transferring data to the printer, the host computer first stores the data in the printer spooler and then transfers the data to the printer. Data is stored in the printer spooler until printing of one page is completed, and if printing is stopped midway, the data is transferred again to the printer side. Such control can be easily realized by the printer driver. Therefore, when the misprint is detected by the print success / failure detecting means, it is possible to eject the misprinted paper in a shifted form with respect to the paper normally printed on the paper ejection tray.

(Third Embodiment) In the above-described second embodiment, when ejecting misprinted paper, the paper is moved by the paper conveying system and ejected. In this embodiment, when the misprinted paper is ejected, the paper ejection tray position control means moves the paper ejection tray and ejects the misprinted paper to the paper ejection tray in the moved state. It is characterized in that the paper is discharged to the tray in a form different from the normal paper discharge.
