Abstract
Abstract In a printer image control system, which temporarily holds an image signal which is to be transmitted to a printer and also controls the printer, an image effective area is determined according to the size of a printing sheet, so that nothing is printed outside the image effective area. Also "white" data can be printed over an unwanted image region of the image signal, to remove the unwanted image region; or when the image signal falls partially outside of the image effective area, the image signal can be contracted to fit on one page or it can be divided to be printed on two pages.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
90 words
A printer image control system for temporarily holding image signal data to be transmitted to a printer and for controlling the printer, said system comprising: means for storing predetermined image effective area data sets according to the size of print sheets; means for selecting an image effective area for a selected size print sheet from predetermined data sets stored in said storing means; means for generating image data exclusively within the image effective area; and means for receiving and printing data within the image effective area on the print sheet.
Claim 2
Dependent Claim
90 words
A printer image control system for temporarily holding image signal data to be transmitted to a printer and for controlling the printer, said system comprising: means for storing predetermined image effective area data sets according to the size of print sheets; means for selecting an image effective area for a selected size print sheet from predetermined data sets stored in said storing means; means for generating image data exclusively within the image effective area; and means for receiving and printing data within the image effective area on the print sheet.
Claim 3
Dependent Claim
54 words
The printer image control system of claim 1, wherein the printer includes: a first sensor for detecting a start of a horizontal scan of the print sheet and for generating a first sensor signal; and a second sensor for detecting the start of the sheet supply feed and for generating a second sensor signal.
Claim 4
Dependent Claim
63 words
The printer image control system of claim 2, wherein the means for generating image data exclusively within the image effective area includes: an image data buffer for containing image signal data wherein said selecting means is responsive to said first and second sensor signals for transferring image signal data exclusively within the image effective area from the image data buffer to the printer.
Claim 5
Dependent Claim
23 words
The printer image control system of claim 1, further including: means for blocking image data which is located outside the image effective area.
Claim 6
Independent Claim
128 words
A method of controlling the printing of an image on a print sheet in a printer using a control system, the method comprising the steps of: detecting a sheet size of the print sheet in the printer; storing a table of image effective areas according to the sheet size of the print sheet; selecting an appropriate image effective width and length for the sheet size from the table of image effective areas; generating a first read enable signal for reading in a horizontal scan direction within the image effective width; generating a second read enable signal for reading in a vertical feed direction within the image effective length; and applying image data to the image effective area only when both first and second read enable signals are generated.
Claim 7
Independent Claim
128 words
A method of controlling the printing of an image on a print sheet in a printer using a control system, the method comprising the steps of: detecting a sheet size of the print sheet in the printer; storing a table of image effective areas according to the sheet size of the print sheet; selecting an appropriate image effective width and length for the sheet size from the table of image effective areas; generating a first read enable signal for reading in a horizontal scan direction within the image effective width; generating a second read enable signal for reading in a vertical feed direction within the image effective length; and applying image data to the image effective area only when both first and second read enable signals are generated.
Claim 8
Dependent Claim
119 words
A printer image control system for temporarily holding image signal data to be transmitted to a printer, said system comprising: means for storing image effective area data according to a size of print sheets; means for determining the size of the print sheet on which to print; means for selecting an image effective area from data stored in said storing means for the determined size of print sheet; means for selecting a portion of said image signal data which is temporarily held which corresponds to a region of an image to be blanked out; and means for writing over the selected portion of said image signal data, to blank out the region of the image to be blanked out.
Claim 9
Dependent Claim
119 words
A printer image control system for temporarily holding image signal data to be transmitted to a printer, said system comprising: means for storing image effective area data according to a size of print sheets; means for determining the size of the print sheet on which to print; means for selecting an image effective area from data stored in said storing means for the determined size of print sheet; means for selecting a portion of said image signal data which is temporarily held which corresponds to a region of an image to be blanked out; and means for writing over the selected portion of said image signal data, to blank out the region of the image to be blanked out.
Claim 10
Dependent Claim
23 words
The printer image control system of claim 6, wherein said writing means includes: means for supplying "0" data to overwrite the image data.
Claim 11
Dependent Claim
167 words
A printer image control system for temporarily holding image signal data to be transmitted to a printer and and for controlling the printer, said system comprising: means for storing image effective area data according to sizes of print sheets; means for determining the size of the print sheet on which to print; means for selecting an image effective area from data stored in said storing means for the selected size of the print sheet; means for detecting whether an area of said image signal data is partially outside the image effective area determined by said selecting means; means for contracting said image signal data to fit within the image effective area of one print sheet; means for dividing said image signal data to fit within the image effective area of two print sheets; and means for selecting one of said contracting and dividing means when the area of said image signal data is partially outside of said image effective area, whereby said image signal is completely printed.
