  Here, the EEPROM 13 will be described with reference to FIGS. As shown in FIG. 2, the EEPROM 13 includes a plurality of storage areas including a mark storage area 131. In the mark storage area 131, information related to a copy discrimination mark (hereinafter referred to as mark information) that is printed together with the content when the content is printed by the printer 3 is stored.

  As shown in FIG. 3, the mark information includes data for specifying the mark, the area corresponding to the mark, and the print position of the mark, and is stored separately for the front side and the back side. Note that the surface of the printing paper on which the content of the content is printed by the printer 3 is referred to as the front surface, and the other surface is referred to as the back surface. As data for specifying the mark, for example, image data of the mark is stored. The front surface mark M1 is a mark printed on the front surface of the paper together with the contents. In the present embodiment, one square mark is used as a whole, which is composed of a total of four squares arranged two in the height direction and two in the width direction. Note that the height direction is a conveyance direction during printing of a sheet, and the width direction is a direction orthogonal to the conveyance direction during printing of a sheet. The back surface mark M2 is a mark printed on the back surface of the paper. In the present embodiment, a mark is used in which a line segment extending outward from each vertex along the diagonal line is added to a square in which diagonal lines are arranged along the height direction and the width direction, respectively. An area corresponding to a mark (hereinafter referred to as a mark area) is an area defined by the height and width at the time of mark printing for each mark. As data for specifying the mark area, for example, the sizes of the mark areas R1 and R2 corresponding to the front surface mark M1 and the back surface mark M2 are stored. Further, as data for specifying the mark printing position, for example, the coordinates of the printing positions of the base point B1 and the base point B2, which are the upper left apexes of the square mark regions R1 and R2, are stored. In the present embodiment, each of the front mark M1 and the back mark M2 does not overlap with the content to be originally printed, and the header portion and the footer portion can be clearly confirmed. Printed in two places. Accordingly, two types of coordinates are stored as the coordinates of the printing positions of the base point B1 and the base point B2.

  Although not shown, in practice, it is necessary to change the size and printing position of the front surface mark M1 and the back surface mark M2 depending on the paper size. Therefore, in the mark storage area 131, the sizes of the mark areas R1 and R2 and the coordinates of the base points B1 and B2 are stored corresponding to the prescribed sizes (for example, A4 and B4) of various sheets. In the present embodiment, the front surface mark M1 and the back surface mark M2 included in the mark information correspond to the “second mark” and the “first mark” of the present invention, respectively. The mark region R1 corresponds to “second position” and “second region”, and the mark region R2 corresponds to “first position” and “first region”.

  Here, with reference to FIG. 4, the positional relationship when the front surface mark M1 and the back surface mark M2 are printed will be described. The front surface mark M1 is printed in the mark region R1 positioned by the base point B1 on the surface of the paper. On the other hand, the back surface mark M2 is printed in a mark region R2 positioned by the base point B2 on the back surface of the paper. FIG. 4 shows a state viewed from the surface of the paper after printing. In the present embodiment, when the front surface mark M1 and the back surface mark M2 are printed on the front surface and the back surface, respectively, as shown in FIG. 4, a square that forms the outer surface of the front surface mark M1 (hereinafter referred to as an “outer square”) The square of the back surface mark M2 is inscribed. That is, each vertex of the square of the back surface mark M2 is on the midpoint of each side of the outer square of the front surface mark M1. The line segment extending from each vertex of the square of the back surface mark M2 is in a state where it is on the same straight line as the side where the squares constituting the outer square of the front surface mark M1 are in contact with each other. At this time, the mark area R1 is included in the mark area R2. Note that the mark region R1 corresponding to the surface mark M1 having a square outline has the same shape as the surface mark M1, and therefore overlaps the surface mark M1 in FIG. In the present embodiment, the printing positions of the front surface mark M1 and the rear surface mark M2 are such that the printed front surface mark M1 and the back surface mark M2 overlap each other and have an appearance like a single mark as a whole. Is preset. More specifically, the print positions of the base points B1 and B2 of the mark areas R1 and R2 are stored in the mark storage area 131. Although details will be described later, when the printed paper is copied, the positional relationship (overlap) between the front surface mark M1 and the back surface mark M2 is shifted, and the appearance of the mark as a whole is seen. Since it changes, it becomes easy to discriminate copies. In particular, the position of each vertex of the square of the mark M2 for the back surface (on the midpoint of each side of the outer square of the mark M1 for the surface) and the position of the line segment extending from each vertex of the square of the mark M2 for the back surface (for the surface) The determination is very easy when there is an easy-to-understand misregistration criterion, such as the side where the squares constituting the outline square of the mark M1 are in contact with each other.

  Next, the memory card 190 connected to the memory card controller 19 will be described with reference to FIGS. As shown in FIG. 2, the memory card 190 includes a plurality of storage areas including a content storage area 191. In the present embodiment, the content storage area 191 stores content files of content downloaded from the server 2 or other external devices connected via the Internet 5. As shown in FIG. 5, the content file is a file including at least title information, copyright information, and a content body. Title information is information that identifies the title of the content. The copyright information is information relating to the copyright holder of the content, permission of use of the content, conditions when the use is permitted, and the like. For example, if the content is an HTML document, information such as the copyright holder can be described using a tag “COPYRIGHT”, and this information can be used as copyright information. The content body is information related to the content, for example, if the content is an HTML document, it refers to information included in the body part. In the following description, for convenience of explanation, it is assumed that a content file of Web content in the HTML document format downloaded from the server 2 by the user of the display terminal 1 is stored in the content storage area 191.

  Below, with reference to FIGS. 6-10, the process performed with the display terminal 1 which concerns on this embodiment is demonstrated. FIG. 6 is a flowchart of the print instruction process. FIG. 7 is an explanatory diagram showing the printing result of the surface. FIG. 8 is an explanatory diagram showing the printing result of the back surface. FIG. 9 is an explanatory diagram of a printing result viewed through the front surface after duplex printing. FIG. 10 is an explanatory diagram of the printing result of FIG. 9 viewed through the front surface when double-sided copying is performed after double-sided printing. The print instruction process shown in FIG. 6 is executed by the CPU 10 according to a program stored in the ROM 11.

  In the print instruction process shown in FIG. 6, the user of the display terminal 1 operates the operation key 16 to select one of the content files stored in the memory card 190 as a print target and instruct the print execution. Then it starts. At this time, the selected content file is read from the content storage area 191 of the memory card 190 and stored in a predetermined storage area (not shown) of the RAM 12. As for the print setting, it is assumed that the printer 3 (see FIG. 1) connected to the display terminal 1 via the USB cable 181 is set as an output destination printer and single-sided printing is set. Such setting information is stored in a predetermined storage area (not shown) of the RAM 12.

  First, the mark information of the back surface mark M <b> 2 is read from the mark storage area 131 of the EEPROM 131 to the RAM 12. As described above, since single-sided printing is designated as the print setting, only the back surface mark M2 is printed on the back surface. Therefore, based on the read mark information of the back surface mark M2, data for back surface printing for causing the printer 3 to perform back surface printing is generated (S1). Specifically, printing data is generated based on the back surface mark M2 and the size of the mark area R2 corresponding to the set paper size and the coordinates of the base point B2. The generated back surface printing data is transmitted to the printer 3 as an instruction to execute printing (S2). Upon receiving this, the printer 3 prints the back surface mark M2 at the two set printing positions (header portion and footer portion) on the back surface of the sheet. The printed result of the back surface mark M2 is as shown in FIG.

  After the data for back side printing is transmitted (S2), the display terminal 1 reads the mark information of the front side mark M1 into the RAM 12. On the surface of the paper, the content of the content selected as the print target (for example, the title and the body) must be printed together with the front surface mark M1. Therefore, data for front surface printing is generated based on the title information and content body of the content to be printed and the mark information of the front surface mark M1 stored in the RAM 12 (S3). As the mark information of the front surface mark M1, the front surface mark M1, and the size of the mark region R1 corresponding to the set paper size and the coordinates of the base point B1 are used as in the back surface mark M2. The generated front surface printing data is transmitted to the printer 3 as a print execution instruction (S4). Upon receiving this, the printer 3 prints the front surface mark M1 at the two set printing positions (header portion and footer portion) on the front surface of the paper, and the contents of the content in the print area. The print result of the front mark M1 and the contents is as shown in FIG. When the data for front side printing is transmitted to the printer 3 (S4), the print instruction process of FIG. 6 ends.

  Thus, when the printer 3 completes the double-sided printing of the paper, the front surface mark M1 and the back surface mark M2 are printed according to the positional relationship shown in FIG. Accordingly, when the entire sheet is viewed through the front surface, as shown in FIG. 9, one mark in which the front surface mark M1 and the back surface mark M2 are exactly overlapped is arranged at two positions on the upper right and lower left of the sheet. Looks like.

  Thereafter, it is assumed that the printed paper as shown in FIG. 9 is copied by an apparatus having a copying function (for example, a copying machine). Since it is considered that the copy person wants to copy only the content content, it is possible to copy only the surface on which the content content is printed. In this case, the back surface mark M2 does not exist on the back surface of the copied paper. Therefore, the copied paper can be easily identified. Further, since the back surface mark M2 is printed on the back surface, it is also conceivable that the printed paper as shown in FIG. In this case, since the paper is reversed during double-sided printing in an apparatus having a copying function, a positional deviation usually occurs between the printing positions during front-side printing and back-side printing. As a result, for example, as shown in FIG. 10, in the copied paper, the overlap between the front surface mark M1 and the back surface mark M2 occurs, and the entire mark that appears when viewed through the watermark is printed by the printer 3. The appearance will be different from that when it is performed (see FIG. 9). Therefore, even when double-sided copying is performed, the copied paper can be easily identified.

  As described above, according to the display terminal 1 of the present embodiment, the data for printing the content and the front mark M1 on the front side of the paper and the data for printing the back side mark M2 on the back side. Are transmitted to the printer 3 and printing is executed. The front mark M1 and the back mark M2 are set to print positions at positions close to each other (for example, overlapping positions) on both sides of the paper, so that when the printed paper is viewed through, it is 1 as a whole. Looks like two marks. Therefore, when the printed paper is copied on one side or on both sides, the paper is seen through the paper due to the positional relationship (overlap) between the front surface mark M1 and the rear surface mark M2. The appearance of the mark recognized as a whole changes, and the copied paper can be easily identified. In particular, since most of the printed contents are copyrighted works, such as when printing for private use, if the contents are used beyond the scope that can be used without obtaining permission from the copyright holder, Infringement. Therefore, for example, when copying of printed paper is not permitted, an unauthorized copy can be easily determined.

  In the present embodiment, the CPU 10 that transmits the data for back side printing to the printer 3 in S2 of FIG. 6 corresponds to the “first print instruction means” of the present invention, and the CPU 10 that transmits the data for front side printing in S4. Corresponds to “second print instruction means”.

<Second Embodiment>
The second embodiment will be described below with reference to FIGS. 11 and 12. FIG. 11 is a block diagram of the display terminal 7 according to the second embodiment. FIG. 12 is a flowchart of the print instruction process according to the second embodiment.

  The display terminal 1 of the first embodiment transmits the data for front side printing and the data for back side printing in all cases regardless of the type of the output destination printer. In this case, if possible, the front-side mark M1 and the back-side mark M2 are printed on both sides of the sheet, so that the copy can be easily identified. However, if the output destination printer is not a printer capable of duplex printing, an error may occur and printing may not be performed when data for duplex printing is transmitted. That is, it may not be necessary to transmit data for double-sided printing. Therefore, the present embodiment is characterized in that different processing is performed depending on whether or not the output destination printer is capable of duplex printing.

  With reference to FIG. 11, the electrical configuration of the display terminal 7 according to the present embodiment will be described. The electrical configuration of the display terminal 7 is the same as that of the display terminal 1 of the first embodiment except for the EEPROM 137. Therefore, components other than the EEPROM 137, which are the same as those of the display terminal 1, are denoted by the same reference numerals in FIG.

  As shown in FIG. 11, the EEPROM 137 of this embodiment has a printer information storage area 132 in addition to the mark storage area 131. The printer information storage area 132 stores information about a printer that can print both the front surface mark M1 and the back surface mark M2 on both sides. Specifically, among various printers distributed in the market, various printer models capable of duplex printing are stored in the printer information storage area 132. The printer model corresponds to the “printing apparatus information” of the present invention.

  Hereinafter, with reference to FIG. 12, a print instruction process performed on the display terminal 7 will be described. The print instruction process in FIG. 12 is executed by the CPU 10 according to the printer stored in the ROM 11. In the following description, it is assumed that the printer 3 is set as the output destination printer and single-sided printing is designated.

  When the process is started, first, the currently set output destination printer model is specified (S11). Specifically, the model of the printer 3 that is the output destination printer is specified from the printer information stored in the RAM 12 at this time. Then, the model of the specified output destination printer is compared with the model stored in the printer information storage area 132 of the EEPROM 137, and it is determined whether or not the printer 3 is a model capable of duplex printing (S13). Specifically, if the same model as the model of the printer 3 is stored in the printer information storage area 132, the printer 3 is determined to be capable of duplex printing (S13: YES). In this case, the same processing as described in the first embodiment is performed. Specifically, first, data for backside printing is generated based on the mark information of the backside mark M2 (S14), and is transmitted to the printer 3 as a print execution instruction (S15). In response to this, the printer 3 prints a back surface mark M2 on the back surface of the paper as shown in FIG. Further, based on the mark information of the front surface mark M1 and the content file of the content to be printed, data for front surface printing is generated (S16) and transmitted to the printer 3 (S17). In response to this, the printer 3 prints the contents and the front surface mark M1 on the surface of the paper as shown in FIG.

  On the other hand, if the same model as the model of the printer 3 is not stored in the printer information storage area 132 and it is determined that the printer 3 is not capable of duplex printing (S13: NO). Printing data is not transmitted to the printer 3. Instead, for example, the printer 15 cannot print the selected content because the printer 3 cannot print the copy determination mark. Specify a printer capable of duplex printing as the output destination. Is displayed (S19). The user of the display terminal 7 who confirmed the message can change the output destination to another appropriate printer. When the output destination is changed to the printer of the model stored in the printer information storage area 132 capable of duplex printing, and the print execution instruction is input again from the operation key 16, the contents and the front mark M1, and Printing data for the back surface mark M2 is transmitted and printing is performed (S13: YES to S17).

  As described above, according to the display terminal 7 according to the present embodiment, printing data is created when the output destination is a printer that cannot print the front surface mark M1 and the back surface mark M2 on both sides of the paper. , Never sent. That is, since the printing data is created and transmitted only when necessary, the processing efficiency can be improved.

  In this embodiment, the CPU 10 that specifies the model of the output destination printer corresponds to the “printing device information acquisition unit” of the present invention in S11 of FIG. 12, and determines whether or not the output destination printer is capable of duplex printing in S13. The CPU 10 that corresponds to the “printing device determination unit”. The CPU 10 that transmits the data for back side printing to the printer 3 in S15 corresponds to the “first print instruction means” of the present invention, and the CPU 10 that transmits the data for front side printing in S17 corresponds to the “second print instruction”. It corresponds to “means”. In addition, the CPU 10 that displays a message on the display unit 15 in S19 corresponds to “first notification unit”.

<Third Embodiment>
The third embodiment will be described below with reference to FIGS. 13 and 14. FIG. 13 is a block diagram of the display terminal 8 according to the third embodiment. FIG. 14 is a flowchart of the print instruction process according to the third embodiment.

  The display terminal 7 according to the second embodiment described above can display the data for front side printing and the back side if the output destination printer can perform double-sided printing regardless of whether the content is content subject to usage restrictions due to copyright. Send data for printing. In this case, the front surface mark M1 and the back surface mark M2 are printed on both surfaces of the paper. However, depending on the performance of the printer 3 (paper conveyance accuracy), positional deviation may occur during double-sided printing, and the front surface mark M1 and the back surface mark M2 may not be arranged in a positional relationship that facilitates discrimination of a copy. sell. For example, if the front surface mark M1 and the back surface mark M2 are in a positional relationship as shown in FIG. However, in the case of double-sided copying, in addition to the paper conveyance accuracy, the document reading accuracy is also added to the cause of the positional deviation. Therefore, it is generally considered that the positional deviation is further increased by the double-sided copying. Therefore, if a positional deviation occurs after copying, the overall appearance of the front surface mark M1 and the back surface mark M2 when viewed through the watermark is still different from the state shown in FIG. It is. However, it is desirable that the front-side mark M1 and the back-side mark M2 are in a state in which the judgment standard for misalignment is easy to understand as shown in FIG. Further, for example, since the paper on which the front surface mark M1 and the rear surface mark M2 are printed is thick, if the back surface mark M2 cannot be identified when viewed through the front surface, an appropriate copy cannot be identified. There may be cases. In addition, the copyright holders are free to perform various acts stipulated in the Copyright Act (including printing and copying), transfer, and other acts, regardless of profit or non-profit, by the copyright owner ( (Hereinafter referred to as free use) may be permitted. In such a case, it may not be necessary to determine the copy.

  For the above reasons, the present embodiment is characterized in that different processing is performed depending on the performance of the printer 3, the type of paper, and whether or not the content to be printed can be freely used. In the following description, watermark printing refers to printing in a state where a print target printed on one side of the paper can be seen through the other side of the paper and can be identified from the other side.

  With reference to FIG. 13, the electrical configuration of the display terminal 8 according to the present embodiment will be described. The electrical configuration of the display terminal 7 is the same as that of the display terminal 7 of the second embodiment except for the EEPROM 138. Therefore, components other than the EEPROM 138 that are the same as those of the display terminal 7 are denoted by the same reference numerals in FIG. 13, and the description thereof is omitted here.

  As shown in FIG. 13, the EEPROM 138 of this embodiment has a paper information storage area 133 in addition to the mark storage area 131 and the printer information storage area 132. In the second embodiment, the printer information storage area 132 stores printer models capable of duplex printing. However, in the present embodiment, duplex printing is possible and substantial when duplex printing is performed. A printer model that does not cause a large misalignment is stored. Note that “no substantial deviation occurs” means that “the deviation of the actual printing position from the original setting position is within an allowable range”. For example, a deviation of 1 mm or less may be regarded as not a substantial deviation. In the paper information storage area 133, information on paper on which watermark printing is possible is stored. Specifically, among the papers of various thicknesses distributed in the market, the product numbers of various papers that can be watermark-printed are stored in the paper information storage area 133. Note that the model of the printer 3 corresponds to “printing apparatus information” of the present invention, and the product number of the paper corresponds to “printing medium information”.

  Hereinafter, the print instruction process performed on the display terminal 8 will be described with reference to FIG. The print instruction process of FIG. 14 is executed by the CPU 10 in accordance with a program stored in the ROM 11. In the following description, it is assumed that the printer 3 is set as the output destination printer and single-sided printing is designated.

  When the process is started, first, the copyright information included in the content file of the content to be printed is referred to. Then, based on the copyright information, it is determined whether the content is subject to usage restrictions due to copyright (S31). For example, if the information described using the tag “COPYRIGHT” stored as copyright information indicates that free use is explicitly permitted, it is determined that there is no usage restriction due to copyright. (S31: NO). In such a case, it is considered that no problem occurs even if the printed paper is copied. Therefore, after the front surface printing data is generated based on the content file of the content to be printed (S46) and transmitted to the printer 3 (S47), the process ends. In response to this, the printer 3 prints only the contents on the surface of the paper. That is, the front surface mark M1 and the back surface mark M2 are not printed.

  If the information stored as copyright information does not explicitly permit free use, it is determined that the content to be printed is content that is subject to usage restrictions due to copyright (S31: YES). In such a case, there is a possibility that printing of the content itself is not permitted, so it is further determined whether printing is possible (S32). For example, if the information stored as the copyright information indicates that all copying is prohibited, it is determined that printing is not possible (S32: NO). In such a case, for example, a message “Since the printing of the selected content is prohibited by the copyright holder, the printing is not performed” is displayed on the display unit 15 (S41), and the processing is performed. finish.

  If the content to be printed is not a non-printable content (S32: YES), the currently set output destination printer model is specified (S33). Specifically, the model of the printer 3 that is the output destination printer is specified from the printer information stored in the RAM 12 at this time. In addition, for the currently set paper (for example, A4), the type of paper set in the printer 3 is acquired (S34). For example, an inquiry about the product number of the paper is transmitted to the printer 3 as information specifying whether the paper is watermark-printable paper, more specifically, the thickness of the paper. Then, the product number of the paper transmitted from the printer 3 in response to the inquiry is stored in the RAM 12. Based on the model of the printer 3 thus specified and the product number of the paper, it is determined whether or not the current output destination printer 3 can perform printing under a predetermined condition (S35). The predetermined condition is that a sheet on which duplex printing can be performed without causing a substantial positional shift of the output destination printer and watermark printing is possible is set. Therefore, if the same model as the model of the printer 3 is stored in the printer information storage area 132, the printer 3 is determined to be capable of duplex printing without causing a substantial positional shift. If the same product number as that of the paper set in the printer 3 is stored in the paper information storage area 133, it is determined that watermark printing is possible. If at least one of the model of the printer 3 and the product number of the paper is different, it is determined that printing under a predetermined condition is impossible (S35: NO). In this case, for example, the copy determination mark cannot be printed on the display unit 15 because “the printer 3 cannot perform double-sided printing or the paper is too thick. Therefore, the selected content is not printed. Is displayed (S41), and the process ends.

  On the other hand, if it is determined that printing is possible under the predetermined conditions (S35: YES), the content content and the front surface mark M1 are printed on the front surface of the paper, and the back surface is the same as in the first and second embodiments. An instruction to print the back surface mark M2 is issued. Specifically, first, data for back surface printing is generated based on the mark information of the back surface mark M2 (S36), and is transmitted to the printer 3 as a print execution instruction (S37). In response to this, the printer 3 prints a back surface mark M2 on the back surface of the paper as shown in FIG. Further, data for front side printing is generated based on the mark information of the front side mark M1 and the content file of the content to be printed (S38) and transmitted to the printer 3 (S39). In response to this, the printer 3 prints the contents and the front surface mark M1 on the surface of the paper as shown in FIG. When the data for front side printing is transmitted, the print instruction process in FIG. 14 ends.

  As described above, in the display terminal 8 according to the present embodiment, printing data is transmitted only when the output destination printer is a printer that does not cause a substantial shift in printing position during duplex printing. Accordingly, since the positional accuracy when the front surface mark M1 and the back surface mark M2 are printed is improved, it is further easy to discriminate the copy. Also, the print data is transmitted only when the paper set in the output destination printer is a paper that can be watermark-printed. Therefore, it is possible to prevent printing in a form in which watermark printing cannot be performed and a copy cannot be identified. Further, when printing is not performed, a notification to that effect is given, so that the user can change the output destination printer or paper to an appropriate one.

  Further, in the display terminal 8 according to the present embodiment, when it is determined that the free use of the content is permitted based on the copyright information included in the content to be printed, the printing data is not transmitted. If the content can be freely used without the permission of the copyright holder, there will be no problem even if the paper after the content is printed is further copied. That is, since the printing data is transmitted only when necessary, the processing efficiency can be improved. Further, when it is determined that the content to be printed can be freely used, the display terminal 8 can print only the content without printing the front surface mark M1 and the back surface mark M2. That is, since the print instruction is automatically switched based on the copyright information, it is possible to cope with printing of a wide range of contents.

  Furthermore, when free use of the content to be printed is not permitted, the print data is transmitted only when the content is permitted to be printed based on the copyright information. If printing is not permitted, printing the content itself becomes a problem. Therefore, it is possible to avoid a situation in which the user's own content printing act causes unauthorized use of the content. Since content that is not permitted to be printed is not printed and is notified of this, the user can take measures such as applying to the copyright holder of the content as necessary.

  In this embodiment, the CPU 10 that determines whether or not there is a usage restriction due to copyright for the content to be printed in S31 of FIG. 14 corresponds to the “usable determination unit” of the present invention. In S32, the content to be printed CPU 10 that determines whether or not printing is possible corresponds to “printing permission determination means”. In S33, the CPU 10 that specifies the model of the output destination printer corresponds to the “printing device information acquisition unit” of the present invention, and the CPU 10 that acquires the type of the paper set in S34 includes the “printing medium information acquisition unit”. Is equivalent to. The CPU 10 that determines whether printing under a predetermined condition is possible in S35 corresponds to a “printing device determination unit” and a “print medium determination unit”. The CPU 10 that transmits the data for back side printing to the printer 3 in S37 corresponds to the “first printing instruction means” of the present invention, and the CPU 10 that transmits the data for front side printing in S39 corresponds to the “second printing instruction”. The CPU 10 that corresponds to “means” and transmits the surface printing data of only the content in S47 corresponds to “third print instruction means”. Further, the CPU 10 that displays the message on the display unit 15 in S41 corresponds to “first notification unit”, “second notification unit”, and “third notification unit”.

  Note that the configuration of the print document management system shown in the above-described embodiment is an exemplification, and it goes without saying that the present invention can be modified in various ways. For example, in the first to third embodiments described above, only the state of seeing through the front side of the paper after double-sided printing is illustrated as the print result, but the copy is similarly seen from the back side of the paper. Needless to say, it is possible to discriminate.

  In the first to third embodiments described above, only the case where the print setting is single-sided printing has been described. However, when double-sided printing is designated, the content for the back side is added to the back side of the paper together with the contents. It is only necessary to generate back side print data for printing the mark and transmit it to the printer 3 to execute printing. In addition, when the print setting is single-sided printing, an example is described in which the reverse side is printed first and the front side is printed later as the order of performing double-sided printing. However, there is no particular limitation as to which side of the paper the print data is transmitted first. However, if the front-side mark is printed on the front side of the paper together with the content, the back-side mark may not be printed on the back side for some reason, such as a paper jam error. On the other hand, when printing is stopped after only the back side has been printed, the content that is the original print target has not been printed, and thus the user is likely to print again. Therefore, by transmitting the data for back side printing first, it is possible to reduce the possibility of printing in a form in which a copy cannot be identified.

  In the first to third embodiments described above, the portable display terminal is exemplified as the print instruction apparatus of the present invention, but the print instruction apparatus of the present invention is not limited to the portable display terminal. . For example, a general-purpose computer device (so-called personal computer) may be employed instead of the display terminal.

  The mark printed together with the content content on the front side of the paper and the mark printed on the back side need to be in the form of the front-side mark M1 and the back-side mark M2 in the first to third embodiments described above. There is no. Specifically, the shape of the mark for the front surface and the back surface is not particularly limited. However, when viewed through one side of the paper, both marks constitute a mark that is identifiable as a whole, and when the two-sided copy is made thereafter, the positional relationship between the two will shift, resulting in the appearance of the mark as a whole. It is desirable that it is easy to determine that the change has occurred. Further, when double-sided printing is performed, it is not necessary that the front-side mark and the back-side mark overlap completely as shown in FIG. In FIG. 4, the mark region R1 of the front surface mark M1 is included in the mark region R2 of the back surface mark M2, but the mark region of the front surface mark and the mark region of the back surface mark are at least one. The parts may overlap. Furthermore, the distance between the mark for the front surface and the mark for the back surface only needs to be within a predetermined range even if at least a part of the mark areas do not overlap each other. In the above-described embodiment, the front surface mark M1 and the back surface mark M2 are arranged at two locations on the diagonal line of the paper. However, the number and position of the front surface and back surface marks are particularly limited. There is no. For example, the front surface mark M1 and the back surface mark M2 may be printed only in the upper left header portion as viewed from the front surface.

  Hereinafter, another example of marks that can be employed will be described with reference to FIGS. FIG. 15 is an explanatory diagram of the surface mark M3. FIG. 16 is an explanatory diagram of the back surface mark M4. FIG. 17 is an explanatory diagram of a printing result viewed through the front surface after duplex printing. FIG. 18 is an enlarged view of the upper right portion of the print result of FIG. FIG. 19 is an explanatory diagram of the front surface mark M5 and the back surface mark M6. FIG. 20 is an explanatory diagram of a printing result viewed through the front surface after duplex printing. FIG. 21 is an explanatory diagram of the print result of FIG. 19 viewed through the front surface when double-sided copying is performed after double-sided printing.

  As shown in FIG. 15, the front surface mark M3 is a white square in which diagonal lines are arranged in the height direction and the width direction of the paper, and the mark region R3 and the base point B3 are as illustrated. On the other hand, as shown in FIG. 16, the back surface mark M4 is a black square in which diagonal lines are arranged in the height direction and width direction of the paper, and the mark region R4 and the base point B4 are as illustrated. The mark regions R3 and R4 have the same size, and the base point B3 and the base point B4 are set so that the front surface mark M3 and the back surface mark M4 have the positional relationship shown in FIG. ing. As shown in FIG. 18, the mark regions R3 and R4 are arranged along the edge of the sheet in contact with each side, and the front surface mark M3 and the back surface mark M4 are connected at the apex of the diamond mold. Configure the appearance like this. When the paper on which the front surface mark M3 and the rear surface mark M4 are printed on both sides is viewed through the front surface, as shown in FIG. 17, the diamonds connected at the vertices are arranged like a frame surrounding the four sides of the paper. It becomes the state. In this way, by arranging a large number of marks along the four sides of the paper, it is possible to more easily determine the positional deviation that occurs when copying on both sides.

  As shown in FIG. 19, the front surface mark M5 and the back surface mark M6 are the same mark consisting of five lines arranged in parallel in the width direction of the paper. Further, the upper right end position of each mark is set as base points B5 and B6 for specifying the printing position of each mark. Note that no mark area is specified for the front surface mark M5 and the back surface mark M6. The base points B5 and B6 are set such that the front surface mark M5 and the back surface mark M6 are in the positional relationship of FIG. 20 when each mark is printed on both sides. That is, the base point B5 and the base point B6 are in a positional relationship in which the distance between the two on the paper is d, and the line segment connecting both is parallel to the upper edge of the paper. The distance d may be determined in advance within a predetermined range. Specifically, the predetermined range is a range in which the positional relationship between the front mark M5 and the back mark M6 can be clearly recognized when viewed through the paper. This is because if the two are too far apart, it will be difficult to discriminate even if a positional deviation occurs after copying. The range in which the positional relationship of the mark can be clearly recognized varies depending on the size and shape of the mark, but can be within 5 mm, for example. By setting the distance d within such a predetermined range, as shown in FIG. 21, when the printing result of FIG. In the example of FIGS. 19 to 21, the base point B5 corresponds to the “second position” of the present invention, and the base point B6 corresponds to the “first position”.

  In the third embodiment described above, the information described using the “COPYRIGHT” tag used in the HTML document is used as copyright information to determine whether the content to be printed is a freely available content. It is an example. However, information other than information described using the “COPYRIGHT” tag can also be used as copyright information. For example, in recent years, various organizations have proposed various marks in order to specify copyright information of contents on the Internet. Therefore, among the proposed marks, a mark indicating that free use is permitted (hereinafter referred to as a free use mark) can be stored in a predetermined storage area (not shown) of the EEPROM 13, for example. Then, it is determined whether or not the content to be printed includes a free use mark stored in the EEPROM 13, and if the free use mark is included, it is determined that the content is permitted for free use. That's fine. In this case, the free use mark included in the content corresponds to “copyright information” of the present invention.

  In addition, for example, for the articles posted on the site, it is possible to store a site on the Internet (hereinafter referred to as a free use site) that explicitly indicates that free use is permitted. If the content to be printed is downloaded from a free use site, it can be determined that there is no usage restriction due to copyright. Specifically, if information (for example, URL) specifying the location on the Internet included in the content to be printed is stored in the EEPROM 13, it is determined that the content is content that can be freely used. Good. In this case, the information specifying the location on the Internet included in the content corresponds to the “copyright information” of the present invention.

  In the third embodiment described above, printing is not performed for content that is prohibited from being copied at all based on copyright information. However, even content that cannot be copied at all can be printed without the permission of the copyright holder within the scope of private use. Therefore, in S41 of the print instruction shown in FIG. 14, instead of the message that the printing is not performed, a message that prompts the user to confirm whether or not the personal use is used is displayed on the display unit 15, and the operation key 16 allows me to When it is input that the use is intended, the processing of S33 to S39 may be performed. In addition, when the copyright holder specifically identifies and permits use by copying and distribution, there is no particular problem in performing printing and copying. Therefore, after S32, based on the copyright information, it is determined whether or not use by copying and distribution is permitted. If it is determined that the content is permitted, the contents are processed by the processing of S46 to S47. Only the contents may be printed.
