The connection cable 103 connects the printing apparatus 101 and the print control apparatus 102. FIG. 2 shows the printing apparatus 1.
01 is shown. Reference numeral 201 denotes a printer main body that can print only one side of a sheet. Paper feed cassette 20
Reference numeral 2 is for setting paper to be printed, and the paper discharge tray 203 holds the paper after printing.

The printing apparatus main body 201 is the printing control apparatus 10
In accordance with the command No. 2, the paper is fed from the paper feeding cassette 202, the odd or even pages are printed, and the paper ejection tray 203
Eject the paper.

FIG. 3 shows the print controller 102.
Reference numeral 301 is a main body of the print control apparatus, and 302 is, for example,
It is a device such as a CRT display device, and displays the print state such as the print document name and the number of pages of the print document. Also, 303 is
For example, a device such as a keyboard is used to start printing and specify a print document.

As an example, a case will be described in which front and back double-sided printing of a document of all eight pages as shown in FIG. 4 is performed. The print control device 102 causes the display device 302 to display a print condition setting screen as shown in FIG. 5, and uses the input device 303 to specify that double-sided printing is to be performed. When the execution of printing is instructed by inputting the execution key existing in the input device 303, the print control device main body 301 sequentially sends the print data of page 1, page 3, page 5, page 7 to the printer device main body 201. Print it. The printer body 201 is a paper feed cassette 202.
Further, the paper is fed, the odd-numbered pages 1 to 7 are printed on the upper surface of the paper, and the paper is ejected with the printing surface facing the ejection tray 203.

When the printing on the front side is completed, a screen as shown in FIG. 6 is displayed on the display device 302 requesting that the paper be turned over and set. The operator reverses the printed paper on the front surface ejected to the paper ejection tray 203, sets it again in the paper feed cassette 202, and uses the input device 303 to instruct completion of paper setting and start of back surface printing.

The sheets whose printing has been completed on the front side are discharged to the discharge tray 203 in the descending order with the printing surface on the upper side. The paper will be set on, and by sequentially printing 2 pages, 4 pages, 6 pages, 8 pages,
Double-sided printing can be performed as shown in FIG.
