However, according to this traditional approach, the user has to check the document for the existence of any modification and has to find the modified page
On the other hand, you don't want to print all the pages at once, because it will waste resources (such as paper and toner)

[0035] Arrangement of printing devices

[0036] figure 1 is a block diagram showing the basic arrangement of the printing apparatus according to the first embodiment of the present invention. The basic arrangement of the printing apparatus according to the first embodiment is not limited to figure 1 arrangements shown and accordingly can be modified to include other functionally equivalent to those in figure 1 Components of the components disclosed in .

[0037] The CPU 101 executes various controls on components constituting the printing apparatus 100 . The memory 102 can provide a plurality of memory areas, including an area for memorizing and storing programs and related data for the CPU 101 to perform various controls on the components constituting the printing apparatus 100, and an area for memorizing and storing programs for the printing apparatus 100 to perform basic operations. An area for programs and related data, a work area required for the CPU 101 performing v...

[0105] A user can modify a document printed from the image data of the document stored in the memory 102 (ie, an original document) by handwriting. The second embodiment allows updating (ie, overwriting) documents stored in memory 102 with the user's modified documents.

[0106] In order to achieve this purpose, the completion of the image 3 After the processing shown in the flowchart of , CPU 101 controls display section 104 to display on its display screen in response to a user instruction Figure 10 GUI shown in . In the first embodiment, the CPU 101 designates a modified document stored in the memory 102 in advance and controls the scanner 109 to read the original document, as described in reference image 3 The explanation given by the flowchart shown in .

[0107] The second embodiment differs from the first embodiment in operation. In the second embodiment, first, the CPU 101 stores an original document in the memory 102 . Then, the CPU 101 inputs the modified doc...

[0117] Although not specifically described, the printing apparatus 100 in the first or second embodiment has only one discharge port (or opening) from which the recording medium on which the recording result is printed can be discharged. On the other hand, the printing apparatus according to the third embodiment has two release ports (or openings). The printing device discharges the modified page from among the plurality of pages constituting the modified document from one discharge port, and discharges the original page from the other discharge port.

[0118] The printing apparatus 100 according to the third embodiment has a capability of delivering a page (that is, a page in a document) placed in an ADF (Automatic Document Feeder) equipped for the scanner 109 to a designated discharge port, or The ability to feed paper released at the release port of the ADF to the designated release port.

[0119] Figure 12 is a flowchart showing printing processing according to the thir...

Abstract

The invention provides a printing apparatus, an image processing apparatus, and a related control method, according to which a modified page can be easily identified when a modified document is printed. First document data and second document data modified from the first document data are obtained by a scanner or received via a network from an external apparatus. One page of the first document data is compared with a corresponding page of the second document data. Then, based on a result of comparison, a modified page included in the second document data is identified as a page containing at least one portion different from a corresponding page included in the first document data. Then, only the modified page is printed.

Description

technical field [0001] The invention relates to a printing device, an image processing device and a related control method. Background technique [0002] When the user prints a modified document including at least one modified page, the user may directly select the modified page so that only the selected page is printed. Otherwise, the user must print all pages of the modified document. However, according to this traditional method, the user has to check the document for the existence of any modification and has to find the modified page. On the other hand, it is not desirable to print all the pages at once because resources (such as paper and toner) are wasted. [0003] In order to solve the above-mentioned problems, a conventional technique (for example, as discussed in Japanese Patent Application Laid-Open No. 08-129549), proposes to place an identifier (version information) on each page, and respond to each The revised version is updated. According to this method, a ...
