(Operation)
With the above configuration, the image forming apparatus 1000 according to the first exemplary embodiment operates as follows. This operation will be described with reference to the operation flowchart of FIG.

(Setting operation)
First, the character type 320 and the allowable value 330 are set as the stored data 3000 in association with the user information 310 in the allowable value storage unit 161 by the allowable value setting program 153 (step S110).

(Printing operation)
Next, as a printing operation, the print data 4000 received by the receiving unit 110 is analyzed by the print data analysis program 152 (step S111). Then, it is determined whether the print data 4000 includes characters and reduced printing (step S120). If the characters are included and reduced printing is performed, user information 310 is acquired from the print data 4000 (step S121).

  On the other hand, if the character is not included or if it is not reduced printing, it is not necessary to check the character size, and the process proceeds to the printing process by the printing unit 141 (step S171).

  Next, it is determined whether there is information that matches the user information 310 acquired in step S121 with the user information 310 of the stored data 3000 (step S130). When the user information 310 included in the print data 4000 includes information that matches the user information 310 of the stored data 3000, the character type 320 and the allowable value 330 associated with the user information 310 are acquired from the stored data 3000 (step S131). ), The page reduction ratio, the character type, and the character size are acquired from the print data 4000 (step S132), and the reduced character size is calculated (step S133).

  On the other hand, if there is no match with the user information 310 of the stored data 3000 in step S130, the character size tolerance is not set and printing may be performed as it is. It skips and it transfers to a printing process (step S171). If there is no match in step S130, the process does not proceed to step S171, but the processes after steps S133 and S150 are performed using the character size for each predetermined character type determined separately as a reference value. Also good.

  Next, it is determined whether or not the character type included in the print data 4000 matches the character type 320 of the user information 310 registered in the storage data 3000 (step S140). If there is a matching character type 320, the character size comparison program 154 determines whether the reduced character size calculated in step S133 is smaller than the allowable value 330 (step S150).

  If the reduced character size is smaller than the allowable value 330, printing is stopped (step S151), the state of the image forming apparatus 1000 is notified by the notification program 155 (step S152), and the operator is asked whether or not to continue printing. Select (step S160).

  If printing is to be continued, it is determined whether all character types included in the print data 4000 have been checked (step S170). If all character types have been checked, the printing unit 141 performs print processing (step S171). If all the character types have not been checked, the process returns to step S132 to determine the next character type from the print data 4000. The character size is obtained and the reduced character size is calculated, and the character size check is repeated in the same manner.

  On the other hand, if there is no character type included in the print data 4000 that matches the character type 320 of the stored data 3000 in step S140, it is not necessary to check the character size, and in step S150. If the reduced character size is larger than the allowable value 330, there is no need to notify that the character is too small, so the check is skipped and the process proceeds to print processing (step S171).

(Operation according to the operation procedure)
Next, according to the operation sequence of the operator using the example of the allowable value setting screen of FIG. 7, the example of the stored data of the storage data of FIG. 8, the example of the printed result of FIG. 9, and the example of the alert screen of FIG. The operation of the image forming apparatus 1 will be described in more detail.

  In the following description, the user information 310 is user A, the character type 320 is three types of font 1, font 2, and font 3, and the allowable value 330 is registered as 6 points, 6 points, and 4 points, respectively. A process when the print data 4000 includes a character type 320 of font 2, a character size of 8 points, and a reduction ratio of 70% will be described.

  First, the operator uses the user information tag 210 shown in FIG. 7, the character information tag 220 for setting the four character types 320 and the allowable value 330, and the allowable value setting screen 2000 including the allowable value tag 230. 210. Four character type tags 220 and allowable value tags 230 are set as indicated by “*” from the respective lists, and a setting completion button 240 is pressed.

  Then, as shown in the stored data 3000 in FIG. 8, as the information specified on the setting screen 2000, the user information 310 is user A, the character type 320 is font 1, font 2, font 3, and the allowable value 330. 6 points, 6 points, and 4 points are stored in the stored data 3000.

  FIG. 9 is a view showing an example of a print output when printing is performed after setting as described above. In the same size printing, the character type 320 is font 2 and the character size is 8 points. However, in the reduced printing with a reduction rate of 70%, the character size is printed as a small character equivalent to 5.6 points. Even after printing, the characters are crushed and cannot be read.

  In this example, since the allowable value 330 of the font 2 is set to 6 points, the printing is stopped assuming that there is a font smaller than the reference font size, and the character type 320 is the font 2 as shown in FIG. Information indicating that characters smaller than 6 points of the allowable value 330 are printed, and a message prompting the user to specify whether to continue printing or cancel are displayed on the message display unit 510. Although not shown, a reduction rate may also be displayed and a message prompting to increase this may be displayed.

  Then, if the characters may be crushed and printed, the operator selects “print as it is” 520 and performs printing. Alternatively, if you want to change the font size or reduced size and perform printing again, select “Cancel printing” 530, cancel printing, change the font size, etc., then print. To do.

(Effect of Example 1)

Therefore, a desired allowable value for the font size at the time of printing is set for each user. It can be set, and wasteful printing desired by the user can be prevented.

  In the image forming apparatus according to the second embodiment, an already registered user allowable value can be selected and set as an allowable value.

(Constitution)
The configuration of the image forming apparatus according to the second embodiment will be described with reference to FIGS. First, FIG. 11 is a block diagram of an image forming apparatus 1000 according to the second embodiment. The image forming apparatus according to the second embodiment is different from the image forming apparatus according to the first embodiment in the configuration in the program ROM 150. Since other configurations are the same as those of the first embodiment, description thereof is omitted for the sake of brevity.

  The program ROM 150 of the image forming apparatus according to the second embodiment has a configuration in which a setting value acquisition program 610 for acquiring the character type 320 and the allowable value 330 associated with the user information 310 from the stored data 3000 is added.

  With this configuration, in the first embodiment, when the character type 320 and the allowable value 330 are set by the allowable value setting program 153, the setting value on the setting screen 2000 is set as the allowable value. In Example 2, the character type 320 and the allowable value 330 associated with the registered user information 310 in the storage data 3000 stored in the allowable value storage unit 161 of the image forming apparatus 1000 can be set as the reference values. .

  FIG. 12 is a configuration diagram illustrating a setting screen 2000 according to the second embodiment. In the image forming apparatus according to the second embodiment, by selecting user information by the user information tag 210, the character type 320 and the allowable value 330 associated with the registered user information 310 in the storage data 3000 are acquired, and the character type tag 220 is acquired. And a setting value acquisition button 710 for reflecting in the allowable value tag 230 is added.

  The operator changes the character type tag 220 and the allowable value tag 230 as needed, and stores the character type 320 and the allowable value 330 in the allowable value storage unit 161 in association with the user information 310 by pressing the setting completion button 240. Is done. Note that the configurations of the storage data 3000, the print data 4000, and the alert screen 5000 in the second embodiment are the same as those in the first embodiment, and thus the description thereof is omitted for the sake of brevity.

(Operation)
FIG. 13 is a flowchart illustrating the operation of the image forming apparatus according to the second embodiment. In the image forming apparatus according to the second embodiment, the processes of step S210 and step S211 for setting the character type 320 and the allowable value 330 are newly added. Since the processing after step S110 is the same as the operation of the image forming apparatus of the first embodiment, it will be described in a simplified manner.

(Setting operation)
First, it is determined whether or not the setting value associated with the registered user information 310 in the stored data 3000 is acquired (step S210), and the setting value associated with the registered user information 310 in the stored data 3000 is determined. In the case of acquisition, the set value acquisition program 610 acquires the character type 320 and the allowable value 330 associated with the registered user information 310 in the storage data 3000, and sets them as the set values (step S211).

  On the other hand, when the setting value associated with the registered user information 310 is not acquired, the allowable value setting program 153 associates the character type 320 and the allowable value 330 with the user information 310 in the allowable value storage unit 161 as the stored data 3000. Set (S110).

(Printing operation)
Next, as a printing operation, the print data 4000 received by the receiving unit 110 is analyzed by the print data analysis program 152 to determine whether the print data 4000 includes characters and whether or not reduced printing is performed. In the case of reduced printing, user information 310 is acquired from the print data 4000 (steps S111, S120, and S121). On the other hand, if the character is not included or if it is not reduced printing, it is not necessary to check the character size, and the process proceeds to the printing process by the printing unit 141 (step S171).

  Next, it is determined whether or not the user information 310 acquired in step S121 matches the user information 310 of the storage data 3000. If there is matching information, the character type 320 associated with the user information 310 from the storage data 3000 is determined. And the allowable value 330 are acquired, the page reduction rate, the character type, and the character size are acquired from the print data 4000, and the reduced character size is calculated (steps S130 to S133).

  On the other hand, if there is no match with the user information 310 of the stored data 3000, the process proceeds to print processing (step S171). As in the first embodiment, when there is no matching user information, the same processing may be performed using a character size for each predetermined character type determined separately as a reference value.

  Next, it is determined whether the character type included in the print data 4000 matches the character type 320 of the stored data 3000. If the character type 320 matches the character type 320 of the stored data 3000, the calculated reduced character size is the allowable value. It is determined whether it is smaller than 330 (steps S140 and S150).

  If the reduced character size is smaller than the allowable value 330, printing is stopped, notification to that effect is made, the operator selects whether to continue printing, and if printing is continued, it is included in the print data 4000. It is determined whether or not all character types have been checked, and when all the character types have been checked, the process proceeds to print processing (steps S151, S152, S160, S170, and S171).

  On the other hand, if there is no character type included in the print data 4000 that matches the character type 320 of the stored data 3000, or if the reduced character size is larger than the allowable value 330, the process proceeds to print processing (step S100). S171).

(Operation according to the operation procedure)
Next, the operation of the second embodiment will be described in more detail using the configuration diagram of the allowable value setting screen in FIG. 14 and the stored data example of the stored data in FIG.

  In the following description, there is a set value corresponding to the stored data 3000, the user information 310 is the user A, the character type 320 is three types of font 1, font 2, and font 3, and the allowable value 330 is set. This is registered as 4 points, 4 points, and 3 points, respectively, and the print data 4000 will be described as processing when the character type 320 is font 2, the character size is 8 points, and the reduction rate is 40%. .

  First, the operator uses the user information tag 210 and the allowable value setting screen 2000 including the character type tag 220 and the allowable value tag 230 for setting the four character types 320 and the allowable value 330 shown in FIG. By setting the user A from the user information list 260 to 210 and pressing the set value acquisition button 710, the set value associated with the user A is reflected in the character type tag 220 and the allowable value tag 230. Then, the setting values (* mark) in the user information list 260, the character type list 270, and the allowable value list 280 shown in FIG. 12 change to the setting values shown in FIG.

  As shown in the stored data 3000 of FIG. 15, as information specified on the setting screen 2000, user information 310 is user A, character type 320 is font 1, font 2, font 3, and allowable value 330. The stored data 3000 is stored as 4 points, 4 points, and 3 points.

  Based on the above setting, when printing is performed, the character type 320 is font 2 and the character size is 8 points in the same size printing, whereas the reduced font size is 40% in the reduced printing with the reduction rate of 40%. Since it is printed as a small character equivalent to 2 points, the character is crushed and cannot be read even if it is folded.

  In this example, since the allowable value 330 of the font 2 is set to 4 points, printing is stopped assuming that there is a font smaller than the reference font size, and the character type 320 is allowed to be the font 2 as in FIG. Information that characters smaller than four points of value 330 are printed and a message that prompts the operator to specify whether to continue printing or cancel are displayed on message display unit 510.

  Then, as in the first embodiment, when the characters may be crushed and printed, the operator selects “print as it is” 520 and performs printing. Alternatively, if you want to change the font size, etc., or change the reduced size and perform the printing process again, select “Cancel Printing” 530 to cancel printing once and change the font size, etc. Start printing.

  In the above description, it has been described that the user is set from the user information list of the user information tag, and the character type tag and the allowable value tag are acquired by simply pressing the set value acquisition button. Or a password may be entered.

(Effect of Example 2)
As described above, according to the image forming apparatus of the second embodiment, the character type and the allowable value associated with the registered user information are selected and set as the allowable value information, and the font size at the time of printing is set to the allowable value. Since the determination is made based on the information and a predetermined warning is given, in addition to the effects of the first embodiment, the registered information can be used effectively, and the setting operation of the allowable value can be simplified.

  The image forming apparatus according to the third embodiment can register a font size corresponding to a character type to be warned for each of a plurality of users.

(Constitution)
The configuration of the image forming apparatus according to the third embodiment will be described with reference to FIGS. FIG. 16 is a block diagram of the image forming apparatus according to the third embodiment. In the image forming apparatus 1000 of the third embodiment, the contents of the program ROM 150 are different from those of the second embodiment, and a group information setting program 810 is newly added.

  By adding the group information setting program 810, the character type 320 and the allowable value 330 are stored in association with the user information 310 as shown in FIG. 15 in the second embodiment, whereas the image forming apparatus of the third embodiment is stored. Then, as shown in FIG. 18 described later in detail, the character type 320 and the allowable value 330 are stored in association with the user information 310 and the group information (A10). Other configurations are the same as those of the second embodiment, and thus the description thereof is omitted for the sake of brevity.

  FIG. 17 is a configuration diagram of a screen for setting the group information (A10), the user information 310, the character type 320, and the allowable value 330 by the allowable value setting program 153. In the setting screen 2000 of the third embodiment, a group information tag 910 for setting group information (A10) is added to the configuration of the second embodiment.

  Further, the group information tag 910 has a group information list 920. A “*” mark is added to the current setting value of the list, and all selectable groups are displayed. The operator selects the group information tag 910, the user information tag 210, the character type tag 220, and the allowable value tag 230 from each list, and presses the setting completion button 240, whereby the user information 310 and the group information (A10) are displayed. The character type 320 and the allowable value 330 are stored in the allowable value storage unit 161 in association with each other.

  FIG. 18 is a diagram illustrating a configuration of the storage data 3000 stored in the allowable value storage unit 161 according to the third embodiment. As shown in the figure, the stored data 3000 includes user information 310, a character type 320, and an allowable value 330, as well as group information (A10) for identifying a group and a character type 320 shared by the group information (A10). It is composed of general-purpose users (A20) to which the value 330 is associated.

  FIG. 19 is a diagram illustrating a configuration of print data 4000 according to the third embodiment. As shown in the figure, the print data 4000 is added with group information described by an information command (B10). The other configuration is the same as the configuration of FIG. 4 described in the first embodiment, and thus the description thereof is omitted for simplification.

(Operation)
With the above configuration, the image forming apparatus according to the third exemplary embodiment operates as follows. This operation will be described with reference to the operation flowchart of FIG. In the image forming apparatus according to the third exemplary embodiment, step S319 is added as a process for setting the character type 320 and the allowable value 330, and the step for acquiring the character type 320 and the allowable value 330 from the stored data 3000 is performed. S311, S320, and S321 are added. The other processing is the same as the operation of the second embodiment shown in FIG. 13, and will be described below in a simplified manner.

(Setting operation)
First, as a setting operation, it is determined whether or not a setting value associated with the registered user information 310 in the storage data 3000 is acquired, and the setting value associated with the registered user information 310 in the storage data 3000 is determined. In the case of acquisition, the character type 320 and the allowable value 330 associated with the registered user information 310 in the stored data 3000 are acquired and set as set values (steps S210 and S211).

  On the other hand, when the setting value associated with the registered user information 310 is not acquired, the character type 320 and the allowable value 330 are set as the stored data 3000 in the allowable value storage unit 161 in association with the user information 310 (S110).

  Next, the character type 320 and the allowable value 330 are set in association with the general-purpose user of the group information (A10) by the allowable value setting program 153 (step S310).

(Printing operation)
Next, as a printing operation, the print data 4000 received by the receiving unit 110 is analyzed by the print data analysis program 152 to determine whether the print data 4000 includes characters and whether or not reduced printing is performed. In the case of reduced printing, user information 310 is acquired from the print data 4000 (steps S111, S120, and S121). On the other hand, if the character is not included or if it is not reduced printing, it is not necessary to check the character size, and the process proceeds to the printing process by the printing unit 141 (step S171).

  Next, it is determined whether or not the user information 310 acquired in step S121 matches the user information 310 of the storage data 3000. If there is matching information, the character type 320 associated with the user information 310 from the storage data 3000 is determined. And the allowable value 330 are acquired, the page reduction rate, the character type, and the character size are acquired from the print data 4000, and the reduced character size is calculated (steps S130 to S133).

  On the other hand, when the user information 310 included in the print data 4000 does not match the user information 310 of the stored data 3000, group information (A10) is acquired from the print data 4000 (step S311). Then, it is determined whether or not the group information (A10) included in the print data 4000 matches the group information (A10) of the stored data 3000 (step S320).

  On the other hand, if there is no match with the user information 310 of the stored data 3000 in step S320, the process proceeds to print processing (step S171). As in the first and second embodiments, when there is no matching user information, the same processing may be performed using a character size for each predetermined character type determined separately as a reference value.

  When the group information (A10) included in the print data 4000 matches the group information (A10) of the storage data 3000, the storage data 3000 is associated with the general-purpose user (A20) belonging to the group information (A10). The character type 320 and the allowable value 330 are acquired (step S321).

  Next, it is determined whether the character type included in the print data 4000 matches the character type 320 of the stored data 3000. If the character type 320 matches the character type 320 of the stored data 3000, the calculated reduced character size is the allowable value. It is determined whether it is smaller than 330 (steps S140 and S150).

  If the reduced character size is smaller than the allowable value 330, printing is stopped, notification to that effect is made, the operator selects whether to continue printing, and if printing is continued, it is included in the print data 4000. It is determined whether or not all character types have been checked, and when all the character types have been checked, the process proceeds to print processing (steps S151, S152, S160, S170, and S171).

  On the other hand, if there is no character type included in the print data 4000 that matches the character type 320 of the stored data 3000, or if the reduced character size is larger than the allowable value 330, the process proceeds to print processing (step S100). S171).

(Effect of Example 3)
As described above, according to the image forming apparatus of the third embodiment, a storage unit that stores character types and allowable values in association with group information including a plurality of user information is provided, and is associated with registered user information or group information. Since the selected character type and allowable value are selected and set as allowable value information, the font size at the time of printing is determined based on the allowable value information, and a predetermined warning is given. A common character type and allowable value can be set for a plurality of users, and the setting operation can be further simplified.

<< Other modifications >>
(1) In the above description of the embodiment, the character size has been described as an example of the allowable value. In addition, not only characters but also the size of an outline such as a figure may be set as an allowable value.

  (2) In the above description of the embodiment, the character size is determined in the case of reduced printing. However, the same determination may be performed not only in reduced printing but also in normal printing. Alternatively, although slightly different from the object of the present invention, printing may be interrupted when there is a character larger than a predetermined size, and the size of the character or image may be determined only in the case of enlarged printing. .

  (3) Further, in the above description of the embodiment, it has been described that the determination is based on the allowable value according to the character type. However, one allowable value may be used for all character types, or for each specific plural character type. An allowable value may be set.

  (4) In the above description of the embodiment, it has been described that the font size at the time of printing is determined by the allowable value. However, the font size or the like may be checked when the print output is displayed on the monitor. .

  (5) Further, in the above description of the embodiment, the description has been made so that the warning content is displayed on the alert screen. However, the warning may be made by using sound or the like, or the warning screen may be used together with the alert screen. It may be.

  (6) In the above description of the embodiment, each program is provided in the program ROM in the image forming apparatus and executed by the CPU provided in the image forming apparatus. However, these are provided in the host computer. Alternatively, it may be configured to use a program ROM or CPU of another computer or the like connected via a network.

  The present invention can be widely used in printers, facsimile machines, MFPs (multifunction printers) that combine the above functions together with scanner functions, or image forming apparatuses that print characters, figures, and the like such as copying machines.
