Enlargement / reduction processing unit 14 that enlarges / reduces the expanded image data, print data generation unit 9 that generates print data based on the data generated by the enlargement / reduction processing unit 14, and generation by print data generation unit 9 By having the transmission unit 10 that transmits the generated print data to the printing device 13, the enlargement / reduction can be realized by enlarging / reducing the image data for one page developed in the print control device 15 and printing it. There is.

[0003]

This conventional enlarging / reducing print control device has to receive print data from a workstation or the like and develop print data for one page as image data. It takes a considerable amount of time to develop the image data and to enlarge / reduce the image data for one page after the development to generate the print data, and the printing performance is significantly deteriorated.

An object of the present invention is to take over the conventional function of automatically enlarging / reducing print data on a sheet designated by a user and printing the same, without increasing the print data for one page into image data at high speed. Another object of the present invention is to provide an automatic enlargement / reduction printing control device capable of printing enlarged / reduced print data on a printing device.

[0005]

An automatic enlargement / reduction printing control apparatus of the present invention comprises a receiving section for receiving print data transmitted from an apparatus such as a workstation, and a received data analysis section for analyzing the print data. A received data sheet identification section for identifying a sheet based on the print data analyzed by the received data analysis section, a print sheet selection section capable of selecting a sheet size to be printed, and the selected sheet size displayed A display unit, a character font storage unit storing fonts of various character sizes, and an image data expansion unit for expanding the image data when the print data received by the reception unit is image data. And the paper size identified by the received data paper identification unit and the paper size selected by the printing paper selection unit are compared, and optimal enlargement / reduction is performed. An enlarging / reducing unit that calculates the ratio and selects enlarging / reducing the character pitch, line pitch, and image data and a character font size based on the enlarging / reducing ratio calculated, and print data that generates the print data to be sent to the printing apparatus. A generation unit and a transmission unit that transmits the print data generated by the print data generation unit to a printing device.

[0006]

Next, the present invention will be described with reference to the drawings. Referring to FIG. 1, which is a block diagram showing an embodiment of the present invention, an automatic enlargement / reduction printing control device 12 of this embodiment is
A reception unit 1 that receives print data transmitted from the workstation 11, a reception data analysis unit 2 that analyzes this print data, and a reception data sheet that identifies a sheet based on the print data analyzed by the reception data analysis unit 2. Identification unit 3
A printing paper selection unit 5 capable of selecting a printing paper size, and a display unit 6 displaying the selected paper size.
A character font storage unit 7 in which fonts of various character sizes are stored; an image data expansion unit 8 for expanding image data when the print data received by the reception unit 1 is image data; The paper size identified by the data paper identification unit 3 and the paper size selected by the print paper selection unit 5 are compared to calculate an optimum enlargement / reduction ratio. Enlargement / reduction of image data and enlargement / reduction processing unit 4 for selecting character font size, print data generation unit 9 for generating print data to be sent to the printing apparatus 13, and print data generated by the print data generation unit 9 for printing apparatus. 13 and a transmission unit 10 for transmitting the data to the transmission unit 13.

1 sent from workstation 11
The print data for the lines is received by the receiving unit 1. The received data is analyzed by the received data analysis unit 2, divided into character data, image data and printer control data, and processed so as to be easily processed in the subsequent processing. Based on the processed print data, the received data sheet identification unit 3 converts the printer control data related to the sheet size into print data that can be recognized by the enlargement / reduction processing unit 4 and sends the print data to the enlargement / reduction processing unit 4 for the sheet size. Nothing other than printer control data is sent to the enlargement / reduction processing unit 4 without doing anything. The printing paper selection unit 5 capable of selecting the printing paper size allows the user to select the printing paper size, and the display unit 6 displays the selected paper size. The enlargement / reduction processing unit 4 compares the paper size identified by the received data paper identification unit 3 with the paper size selected by the print paper selection unit 5 to calculate an optimum enlargement / reduction ratio. Image data expansion for acquiring an optimum character size pattern from the character font storage unit 7 storing the character size font and sending it to the print data generation unit 9 and expanding the image data when it is image data. The image data which is expanded by the enlargement / reduction scale using the section 8 and the character data is processed is sent to the print data generation section 9, and when it is the printer control data of the character pitch or the line pitch, the character pitch or Expand line pitch /
Enlargement / reduction according to the reduction ratio is sent to the print data generation unit 9.
The print data sent to the printer 13 is assembled by the print data generator 9 so that the printer 13 can print. The user only specifies the paper size even when printing is performed on the paper different from when the print data is created by transmitting the print data assembled by the printing device 13 to the printing device 13 by the transmission unit 10. Can automatically enlarge / reduce and print at high speed.

[0008]

As described above, according to the present invention,
Analyze print data sent from a device such as a workstation, identify the paper based on the analyzed print data, select the paper size to print, and expand the image data if the print data is image data. , Compares the identified paper size with the selected paper size to calculate the optimum enlargement / reduction ratio, and enlarges / contracts the character pitch, line pitch and image data according to the calculated enlargement / reduction ratio.
By selecting reduction and character font size and sending it to the printing device, one line of data is received instead of the method of expanding one page of data into image data and enlarging / reducing the image data and printing. At this point, if it is character data, the character font size, line pitch and character pitch are enlarged / reduced and transmitted to the printing device. Only when the received data is image data, it is expanded in the image data expansion section and expanded / reduced. By sending the data to the printing device by the printer, it is possible to omit the time to develop the image data for one page, and in the case of character data, the printing data can be sent to the printing device with a smaller data amount than the image data. High-speed printing can be performed because the transmission time can be shortened.
