Therefore, 1.0 is written in the adjustment amount memory 14h (S13).

  On the other hand, when either the fixed upper limit flag 14i or the arbitrary upper limit flag 14j is on (S3: Yes), the user desires printing in the saving mode in which printing is executed based on the upper limit of the printing cost. Therefore, the process proceeds to S4.

  Subsequently, “0” is written in the C dot number counter memory 14b, the M dot number counter memory 14c, the Y dot number counter memory 14d, and the K dot number counter memory 14e (S4), and the image data stored in the image memory 17 is stored. The first page is set as a reference page (S5).

Next, the image data of the reference page is read from the image memory 17 (S6), the number of dots of each color of CMYK is counted for the read image data, and the number of dots for each color is determined as the C dot number counter memory 14b, M Cumulative addition is performed to the values of the dot number counter memory 14c, the Y dot number counter memory 14d, and the K dot number counter memory 14e (S7). When the number of dots is counted for the image data of the first page, the first page is stored in the C dot number counter memory 14b, the M dot number counter memory 14c, the Y dot number counter memory 14d, and the K dot number counter memory 14e. The number of dots of the image data is written as it is, but when the number of dots is counted by referring to the image data of the second page and thereafter, the value is cumulatively added. That is, in the C dot number counter memory 14b, the M dot number counter memory 14c, the Y dot number counter memory 14d, and the K dot number counter memory 14e, the total dot number of the image data stored in the image memory 17 is stored for each color. The Rukoto.

  Next, it is checked whether or not reading has been completed for all pages of the image data stored in the image memory 17 (S8). When reading for all pages has not been completed (S8: No), the next page is set as a reference page (S10), the process proceeds to S6, and image data for the next page is read from the image memory 17 (S6). Then, when reading is completed for all pages of the image data stored in the image memory 17 (S8: Yes), the printing cost (amount) when printing in the normal print mode based on Equation 1 is performed. Is calculated and written to the printing cost memory 14f (S9).

(Formula 1) Amount = Value of K dot counter x Unit price per K dot + Value of C dot counter x Unit price per C dot + Value of M dot counter + Unit price per M dot + Unit price per Y dot + Value of Y dot counter x Unit price per Y dot Here, the unit price per black dot shown in Formula 1 is a value indicating the price of K (black) ink required for printing per dot in the normal print mode, and is stored in the ROM 13 in advance. Specifically, the price per K ink cartridge (for example, 2600 yen) is divided by the number of dots (for example, 442 × 106 dots) that can be printed with one black ink cartridge in the normal print mode. Value (for example, 5.9 × 10 −6). Further, the unit price per C dot, the unit price per M dot, and the unit price per Y dot are values that mean the price of C ink, M ink, and Y ink required for printing per dot in the normal print mode. Stored in advance. Specifically, the price (for example, 2600 yen) per C, M, and Y ink cartridge is set to the number of dots (for example, 442 × 106) that can be printed with one ink cartridge in the normal print mode. The value divided by (dot) (for example, 5.9 × 10 −6).

  Next, it is checked whether or not the value obtained by multiplying the value in the upper limit memory 14g and the value in the page number memory 14a is smaller than the value stored in the printing cost memory 14f (S11). Here, the upper limit value memory 14g stores the upper limit value of the printing cost set by the user for printing per page in the upper limit value setting process of FIG. Therefore, a value obtained by multiplying the upper limit value by the number of pages of the image data is a value indicating the user's budget amount for the current printing.

  When the value obtained by multiplying the value in the upper limit memory 14g and the value in the page number memory 14a, that is, the budget amount, is larger than the printing cost when printing in the normal printing mode stored in the printing cost memory 14f (S11: No) Even if printing is performed using the same amount of ink as in printing in the normal printing mode, printing can be performed within the range of the ink amount corresponding to the budget amount. Therefore, normal printing is performed in the adjustment amount memory 14h. “1.0”, which is the same value as when the mode is selected, is written (S13).

On the other hand, when the value obtained by multiplying the value in the upper limit memory 14g and the value in the page number memory 14a is smaller than the printing cost stored in the printing cost memory 14f (S11: Yes), that is,
When printing is performed using the same amount of ink as in the normal printing mode, if the amount of ink used for printing exceeds the amount of ink corresponding to the budget amount, the value in the page number memory 14a and the upper limit value memory A value obtained by multiplying the value of 14g by the value of the printing cost memory 14f (number of pages × upper limit value / printing cost) is calculated, and the value is written in the adjustment amount memory 14h (S12). That is, the smaller the printing cost (amount) set by the user as the upper limit value, the smaller the value of the adjustment amount stored in the adjustment amount memory 14h, and the amount of ink used for actual printing is suppressed.

  Next, whether or not the adjustment amount calculated in S12 is larger than the minimum adjustment amount stored in the ROM 13, in other words, whether or not the ink amount used for actual printing is changed beyond the maximum change value. (S14). As described above, the smaller the adjustment amount value, the smaller the amount of ink used for actual printing compared to when printing in the normal mode, so if the adjustment amount value is too small, in other words When the amount of ink used for actual printing is greatly changed beyond the maximum change value, the amount of ink used is too small, and the image quality required at the minimum in printing cannot be obtained. Here, the maximum change value is a value obtained by subtracting the adjustment amount from 1.

  When it is determined that the adjustment amount is smaller than the minimum adjustment amount (S14: No), the LCD 5 displays an inquiry as to whether or not the ink amount used in printing may exceed the ink amount corresponding to the budget, The user is informed that sufficient image quality cannot be obtained with the amount of consumables corresponding to the printing cost within the budget (S16). Next, it is checked whether or not there is an instruction that printing may exceed the budget (S17), and when the user instructs printing to exceed the budget by pressing a key (not shown) (S17: Yes). ), The minimum adjustment amount stored in advance in the ROM 13 is written in the adjustment amount memory 14h (S18), and the process proceeds to S19. On the other hand, if the user does not instruct that printing may exceed the budget (S17: No), the value of the adjustment amount memory 14h is not changed, and the process proceeds to S19. Also, when the value in the adjustment amount memory 14h is larger than the minimum adjustment amount (S14: Yes), the process proceeds to S19.

  Next, the first page of the image data stored in the pixel memory 17 is set as a reference page (S19), and the image data of the reference page is read (S20). Next, based on the value of the adjustment amount stored in the adjustment amount memory 14h, the image data read by the printer 25 is printed out (S21). Specifically, compared to the case of printing in the normal print mode, a predetermined proportion of dots corresponding to the value in the adjustment amount memory 14h is thinned out and printed. Therefore, the amount of ink used in actual printing can be reduced so as not to exceed the amount of ink corresponding to the budget amount set by the user.

  For example, when the user sets an upper limit of 1 yen for the printing cost per page and prints 10 pages, the user's budget amount is 10 yen. On the other hand, when the printing cost required for printing in the normal printing mode calculated in the process of S9 is 20 yen, the adjustment amount is 0.5. Therefore, in the printing process of S21, the (normal mode) In this case, dots are thinned out and printing is performed so that printing can be performed with an ink amount of 0.5 × (ink amount required for printing). That is, printing can be performed using an ink amount corresponding to the user's budget (for example, 10 yen), and printing can be performed using the maximum ink amount within the budget.

  Next, it is checked whether printing has been completed for all pages of the image data stored in the image memory 17 (S22). When reading for all pages has not been completed (S22: No), the next page is set as a reference page (S23), and the process proceeds to S20 to read image data for the next page from the image memory 17 (S20). When printing for all pages of the image data stored in the image memory 17 is finished (S22: Yes), the printing process is finished.

  Next, the upper limit setting process shown in FIG. 6 will be described. The upper limit setting process of FIG. 6 is a process that is activated and executed every predetermined time.

  First, it is checked whether or not the fixed upper limit value input button 4a has been pressed (S31). When the fixed upper limit input button 4a is not pressed (S31: No), the process proceeds to S36.

  On the other hand, when the fixed upper limit input button 4a is pressed (S31: Yes), it is checked whether or not the fixed upper limit flag 14i is on (S32). If the fixed upper limit value input button 4a is pressed while the fixed upper limit flag 14i is on, that is, the 1-yen printing mode is selected, the setting of the 1-yen printing mode is intended to be canceled (S32: Yes). The fixed upper limit flag 14i is turned off, the fixed upper limit LED 4c is turned off, and the process proceeds to S36. If the fixed upper limit value input button 4a is pressed while the fixed upper limit flag 14i is off, the user intends to set the fixed upper limit value (S32: No), so the fixed upper limit value flag 14i is turned on. (That is, the 1-yen printing mode is selected), the fixed upper limit LED 4c is turned on, the arbitrary upper limit flag 14j is turned off, and the arbitrary upper limit LED (not shown) is turned off (S33). The fixed upper limit “1” is written in the memory 14g and the process proceeds to S36.

  Next, it is checked whether or not the arbitrary upper limit button 4b has been pressed (S36). If the arbitrary upper limit input button 4b has not been pressed (S36: No), the upper limit setting process ends.

  On the other hand, when the arbitrary upper limit input button 4b is pressed (S36: Yes), it is checked whether or not the arbitrary upper limit flag 14j is on (S37). If the arbitrary upper limit value input button 4b is pressed while the arbitrary upper limit flag 14j is on, that is, the arbitrary upper limit value printing mode is selected, the user intends to cancel the setting of the arbitrary upper limit value. Therefore (S37: Yes), the arbitrary upper limit flag 14j is turned off, the lighting of the arbitrary upper limit LED (not shown) is turned off, and the upper limit setting process ends. If the arbitrary upper limit value input button 4b is pressed while the arbitrary upper limit flag 14j is off, the user intends to set the arbitrary upper limit value print mode (S37: No), so the fixed upper limit flag 14i. Is turned off, the lighting of the fixed upper limit LED 4c is turned off, the arbitrary upper limit flag 14j is turned on, the arbitrary upper limit LED (not shown) is turned on (S38), and the input screen 5a shown in FIG. (S39).

  Next, it is checked whether or not an arbitrary upper limit value has been input from the numeric keypad 4d (S40). If not input (S40: No), the process waits. On the other hand, when an arbitrary upper limit value is input (S40: Yes), the value input by the numeric keypad 4d is overwritten in the upper limit value memory 14g (S41), and the upper limit value setting process is terminated.

  In the present embodiment, the consumable amount calculation means described in claim 1 corresponds to the processing of S7 in FIG. The consumable amount changing means described in claim 1 corresponds to the processing of S12, S13, and S21 in FIG. The printing means described in claim 1 corresponds to the processing of S21 in FIG. The upper limit value print mode selection means described in claim 5 corresponds to the process of S3 in FIG. The comparison means described in claim 6 corresponds to the processing of S11 in FIG. The notification means according to claim 7 corresponds to the processing of S16 in FIG. The minimum consumable amount changing means described in claim 8 corresponds to the processing of S18 in FIG. The minimum consumable amount printing means described in claim 8 corresponds to the processing of S21 in FIG. The print control means according to claim 8 corresponds to the processing of S14 in FIG.

According to the MFP 1 of this embodiment, when specific image data stored in the image memory 17 is printed out in the normal print mode, the necessary consumable amount is calculated according to the number of dots of the image data. A consumable amount calculating means, an upper limit setting means for setting an upper limit value of a printing cost for printing out the specific image data, and a consumable amount calculated by the consumable amount calculating means is the upper limit. Consumable amount calculation means for changing to a consumable amount corresponding to a printing cost that is equal to or less than the upper limit of the printing cost set by the value setting means, and a range of the consumable amount changed by the consumable amount change means Printing means that prints out the specific image data using the consumables in the printer, so that consumables within the consumable amount range corresponding to the set upper limit printing cost are printed. use Since the user has the effect of being able to print at a printing cost budget easily and quickly.

  Further, according to the MFP 1 of the present embodiment, the upper limit setting means has the fixed upper limit button 4a for inputting a predetermined value as the upper limit, so that the user can determine the predetermined value by the fixed upper limit button 4a. Since the given predetermined value can be input as the upper limit value, there is an effect that printing can be performed easily and at a printing cost within a short time budget.

Further, according to the MFP 1 of the present embodiment, the upper limit setting means has the arbitrary upper limit button 4b for inputting an arbitrary value as the upper limit, so that the user can input an arbitrary value as the upper limit according to the budget. Therefore, there is an effect that printing can be performed easily and in a short time at a printing cost within the budget.

  Further, according to the MFP 1 of the embodiment, the consumable amount changing means makes the consumable amount used in printing by the printer 25 substantially equal to the consumable amount corresponding to the upper limit set by the upper limit setting means. In addition, since it is configured to change the amount of consumables used in printing by the printer 25, there is an effect that the user can easily print at a printing cost using the maximum budget in a short time. .

  Further, according to the multifunction machine 1 of the present embodiment, the MFP 1 includes the upper limit value print mode selection unit that selects the print mode for executing printing based on the upper limit value set by the upper limit value setting unit. At this time, when an upper limit is set for the printing cost, the printing mode for executing printing can be selected based on the upper limit value by the upper limit value printing mode selection means, so that printing can be performed easily and at a printing cost within the budget in a short time. There is an effect that can be.

  Further, according to the MFP 1 of the present embodiment, it has a comparison unit that compares the amount of consumables calculated by the consumable amount calculation unit and the upper limit value set by the upper limit value setting unit, and the printing unit compares the comparison unit. When the consumable amount calculated by the consumable amount calculating means is larger than the upper limit value set by the upper limit setting means, the range of the consumable amount changed by the consumable amount changing means Since the specific image data stored in the image memory 17 is printed out using the consumables inside, the amount of consumables calculated by the consumable amount calculation means is determined by the upper limit value setting means. The consumable amount is changed by the consumable amount change means only when the consumable amount corresponding to the set upper limit printing cost is exceeded, so the consumable amount required for actual printing is printed at the upper limit value. Corresponding to cost That is less than the consumable amount, there is an effect that it is possible to print using conventional printing mode and the same amount of consumables.

  Further, according to the MFP 1 of the present embodiment, when it is determined that the amount of consumables changed by the consumable amount changing unit is larger than a predetermined value, the user prior to printing by the printing unit. If you print with the amount of consumables changed by the consumable amount changing means, you can only get printed matter in bad condition without using the necessary minimum amount of consumables. Since the user is notified prior to printing, there is an effect that unnecessary printing is eliminated. In addition, since printing can be performed using the minimum necessary amount of consumables, there is an effect that a printed matter having a minimum quality can be obtained while minimizing the cost.

Further, according to the multi function device 1 of the present embodiment, when the image memory 17 stores image data corresponding to a plurality of pages, the consumable amount calculation means stores the specific image data stored in the image memory 17. The amount of consumables required is calculated according to the total number of dots. The consumable amount changing means sets the total amount of consumables used for printing on a plurality of pages of recording paper by the upper limit setting means. Since the amount of consumables used when printing the specific image data is changed so that the amount of consumables corresponding to a printing cost equal to or lower than the upper limit of the printing cost is set, Since the amount of suppression can be averaged between a plurality of pages, there is an effect that a high-quality output with no variation in quality can be obtained.

  Further, according to the MFP 1 of the present embodiment, the upper limit setting unit is configured to set the upper limit of the printing cost for printing on one page of recording paper. Regardless of the number of pages, the user only needs to set an upper limit based on the budget per page, so even if the data for all pages is not available, printing can be performed sequentially, so printing can be performed at a printing cost within the budget at high speed. There is an effect that can be done.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be done.

  For example, in the present embodiment, the consumable amount calculation means calculates the necessary consumable amount according to the total number of dots of specific image data stored in the image memory 17. For the stored specific image data, the amount of consumables may be calculated according to the number of dots for each image data corresponding to one page. FIG. 7 shows a modification of the printing process shown in FIG. In FIG. 7, the same reference numerals are given to portions common to the printing process of FIG. 5, and only differences from FIG. 5 will be described.

  The processing of S51 and S52 in the flowchart of FIG. 7 corresponds to the processing of S11 and S12 in the flowchart of FIG. 5, but the processing of S11 and S12 in FIG. 5 multiplies the upper limit value by the number of pages. On the other hand, the processing of S51 and S52 in FIG. 7 differs in that the upper limit value is not multiplied by the number of pages. In the flowchart of FIG. 7, this is consumed so that the printing cost required for printing the image data for one page read in S6 in the normal printing mode is equal to or lower than the printing cost of the upper limit set by the user. This is because the quantity is changed. It is checked whether or not the upper limit value exceeds the printing cost (S51). If it is determined that the printing cost does not exceed the upper limit printing cost even if printing is performed in the normal printing mode (S51: No), the adjustment amount memory “1.0” is written in 14h, but if it is determined that the printing cost exceeds the upper limit printing cost when printing in the normal printing mode (S51: Yes), the value in the upper limit memory 14g is set to the printing cost memory 14f. The value divided by the value is written in the adjustment amount memory 14h as the adjustment amount (S52). That is, the printing process of FIG. 7 is different from the printing process of FIG. 5 in that the adjustment amount is calculated for each read image data of one page.

  Subsequently, the read image data is printed based on the adjustment amount calculated in the process of S52 (S20). Next, it is checked whether or not the reading of all pages has been completed (S22). If the reading has not been completed (S22: No), the next page is set as a reference page (S53), and the process returns to S6. That is, the image data of the next page is read, an adjustment amount for the image data of the page is determined, and printing is performed using the adjustment amount.

  According to the MFP 1 of the modified example, the amount of consumables is calculated according to the number of dots for each piece of image data corresponding to one page for the specific image data stored in the image memory 17, and recorded on one page of recording paper. The amount of consumables used for printing is changed so that the amount of consumables corresponding to the printing cost below the upper limit of the printing cost is changed. Each page can be printed at a printing cost within the budget.

  In this embodiment, the printer 25 prints with dots thinned out according to the adjustment amount. However, the printer 25 performs printing by changing the ink discharge amount per dot according to the adjustment amount. May be.

  In this embodiment, the printer 25 is a so-called inkjet printer, but may be a laser printer or an LED printer. In this case, the printer 25 adjusts the amount of toner used for printing by controlling the surface potential value of the photosensitive drum in accordance with the adjustment amount.

  In the present embodiment, the upper limit value of the printing cost for printing the image data for one page is set as the upper limit value. An upper limit value of the total printing cost required for printing the page image data may be set. In this case, a process for determining whether or not the upper limit value is smaller than the printing cost is performed instead of the process of S11 of FIG. 5, and a value obtained by dividing the upper limit value by the printing cost is replaced with the process of S12. Processing to write the adjustment amount in the adjustment amount memory 14h is performed.

  In the present embodiment, when the adjustment amount is smaller than the minimum adjustment amount, the user is inquired whether printing may exceed the budget. However, when the adjustment amount is smaller than the minimum adjustment amount, the LCD 5 It is also possible to display an error and stop printing.

  In the present embodiment, the fixed upper limit button 4a sets 1 yen as the fixed upper limit value. However, the fixed upper limit button 4a is not limited to 1 yen, and other values may be set as the upper limit value. Good.
