2. Description of the Related Art Conventionally, when data is printed by a printer connected to an information processing apparatus, there are a case of printing the entire text in file units and a case of designating an arbitrary page in the file and printing only a designated page. There is. To print only the specified page, switch the display screen of the information processing device to the print mode screen, specify the start page and end page to be printed from the keyboard of the information processing device, and specify batch output or partial print specification. The printing process is performed each time in response to an instruction from the information processing device.

[0003]

In the conventional printer,
In order to print a designated page, even if only one sheet is printed, the data is image-developed by an instruction command from the information processing device CPU, and a start page and an end page to be printed must be designated for each sheet. There is a problem that the operation is troublesome because it does not happen.

Further, since the print command must be input from the information processing apparatus side at all times, it is necessary to switch the display screen of the information processing apparatus side to the printing screen and interrupt the operation each time the printing operation is performed. There was a problem.

[Object of the Invention] An object of the present invention is to eliminate the inconvenience of designating a print page in a range and to directly designate a print page, thereby simplifying printing of only an arbitrary page and resetting it. It is to solve the annoyance.

Further, since the printing page can be designated by the ten-key pad and the display device provided in the printer, the printing work of the designated page can be simplified and the display device on the information processing device side can be displayed for printing. There is no need to switch.

[0007]

A printer according to the present invention comprises an interface receiving section for receiving a command and data from an information processing apparatus through an interface, an analyzing section for analyzing the received command and data and developing the same in a memory, and a memory. It has a print control mechanism for printing the data expanded to, and a mode change switch for changing the print mode, and expands only the data required when expanding the data by a mode change switch or a command of the information processing device, It has a printing function.

Further, the printer is equipped with a ten-key for inputting a print designation page and a display device for displaying the print page input by the ten-key.

[0009]

According to the present invention, print settings such as WP software can be set.
Since it is possible to expand the user's selection of print settings by selecting both the current page range specification and page specification, both long text and full page printing are supported. be able to.

According to the present invention, by adding the function of designating the print page to the printer, it is possible to easily print only the required page.

This is because when the print mode switch added to the printer is selected according to the printing method, the analysis unit that analyzes the data of the printer recognizes this and prints the normal printing method and the designated page printing according to the printing method. You can choose from two types of methods.

Therefore, when it is desired to print only the necessary pages, it is possible to simply perform the designated page selection by the function of the printer without the troublesome designation of the start page and the end page.

For this reason, it is possible to reduce the number of times the print setting is redone, shorten the time for waiting for printing in front of the printer, and eliminate the waste of paper of a page having no data at the time of printing by specifying the page range.

[0014]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
First, the operation of each unit will be described with reference to FIG. 1 when a designated page is printed without modifying the program on the information processing apparatus side.

The print data transmitted from the information processing apparatus 1 is received by the interface receiving section 2 of the printer, analyzed by the analyzing section 3 and expanded into bits in the memory 6.

At this time, the expansion to the memory 6 is different depending on the state of the mode changeover switch 5, and in the normal mode,
A display showing the format of normal printing as shown in the flow of FIG. 2 is displayed in the printer window. In the designated mode, the designated page is displayed in the printer window as shown in the flow chart of FIG.

After the expansion of the print data, in the normal mode, the print control mechanism 4 executes a process of sequentially printing the data for the number of text pages.

In the designated mode, only the pages that need to be printed among the text pages are input by the 10 key on the window of the printer to select only the necessary pages from all the texts, and the remaining texts are Discard. The print control mechanism 4 prints only the selected text.

Next, the operation of each part will be described in the case of performing the page designation printing by designating the print mode by the program of the information processing apparatus 1 side.

The information processing apparatus 1 sends the command sequence for specifying the print mode to the printer before sending the print data. At this time, when the print page designation mode is selected, the print designation page is input from the keyboard on the print designation display screen of the information processing apparatus 1 as shown in FIG.

The transmitted command sequence for designating the print mode is received by the interface receiving section 2 on the printer side, the analyzing section 3 analyzes the command, and holds it in the data analyzing section 3 as print mode information. The data received by the interface receiving unit 2 is selected by the print mode stored in the analyzing unit 3 according to the flow patterns shown in FIGS. To print.

As for the print mode information held in the data analysis unit 3, the next print mode designation command sequence is received by the analysis unit 3 or the mode selection switch 5 of the printer is used.
It is valid until the time when the designated print mode is received after the operation of, and the mode can be selected from both the printer side and the information processing apparatus side.

A liquid crystal display panel or the like can be used as the window as the display means on the printer side.

[0025]

As described above, according to the present invention, the printing can be designated by the mode changeover switch 5 and the command sequence provided in the printer. Therefore, it is possible to designate the printing without modifying the existing program or to easily deal with it. There is an effect that only the specified page can be printed with.

Further, according to the present invention, the print setting of the WP software or the like is set to a method of selecting both the current page range designation and the page designation, so that the user's selection of print settings can be expanded. For long sentences, both full-text printing and individual page printing can be used.

Further, according to the present invention, by adding a print page designating function to the printer, it is possible to easily print only the necessary pages.

This is because when the print mode switch attached to the printer is selected according to the printing method, the analysis unit that analyzes the data of the printer recognizes this and prints the normal printing method and the designated page according to the printing method. You can choose from two types of methods.

For this reason, when it is desired to print only the necessary pages, it is possible to simply perform the designated page selection by the function of the printer without the troublesome designation of the start page and the end page.

For this reason, it is possible to reduce the number of times the print setting is redone, shorten the time to wait for printing in front of the printer, and eliminate the waste of paper on a page having no data when printing by specifying the page range.
