In the aforementioned step S25, the CPU 12 in the printing management apparatus PK increases or reduces the sum of the ordering numbers HM so as to make the sum “790” (=170+190+210+220) of the ordering numbers HM consistent with an integer multiple of one of ordering standard numbers HKM “24”, “100”, “240” and “800”.

Here, the sum “790” of the ordering numbers HM is closest to “800” which is one time as many as the ordering standard number HKM “800”. Moreover, each of the ordering numbers HM is preferably an integer multiple of “100” for a small box in order to make the sum of the ordering numbers HM consistent with “800” for a large box OB (shown in FIG. 6C).

Therefore, the CPU 12 increases the sum of the ordering numbers HM about the users US1 to US4 from “790” to “800” (=800×1). Moreover, the CPU 12 increases the ordering number HM about the user US1 from “170” to “200” (=100×2). In addition, the CPU 12 changes the ordering number HM about the user US2 from “190” to “200” (=100×2). The CPU 12 reduces the ordering number HM about the user US3 from “210” to “200” (=100×2). The CPU 12 further reduces the ordering number HM about the user US4 from “220” to “200” (=100×2). In addition, the CPU 12 serves as a confirmation/resetting section 25 (shown in FIG. 8) to confirm the sum of the ordering numbers HM as “800”.
