Step S21: when having accepted the registration of the business cards MSr1 to MSr4 of the other persons TS1 to TS4 in the step S20, the CPU 12 in the printing management apparatus PK serves as a calculation section 23 (shown in FIG. 8) to reduce the remaining numbers ZM of business cards MSt1 to MSt4 of the users US1 to US4 accordingly respectively in the remaining number database ZMDB (shown in FIG. 15). Thus, the remaining numbers ZM of the business cards MSt1 to MSt4 of the users US1 to US4 are changed from “31” to “21” (=31-10), “24” (=31-7), “26” (=31-5) and “28” (=31-3) respectively, as shown in FIG. 15.

Step S22: when having reduced the remaining numbers ZM of the business cards MSt1 to MSt4 of the users US1 to US4 in the step S21, the CPU 12 in the printing management apparatus PK serves as a comparison section 24 (shown in FIG. 8) to determine whether each of the remaining numbers ZM “21”, “24”, “26” and “28” of the business cards MSt1 to MSt4 of the users US1 to US4 is smaller than a remaining number limit ZGM “30” (shown in FIG. 5) or not. Since each of the remaining numbers ZM “21”, “24”, “26” and “28” is smaller than the remaining number limit ZGM “30” (shown in FIG. 5), processing goes to “YES”.

Incidentally, when each of the remaining numbers ZM is not smaller than the remaining number limit ZGM, the processing goes to “NO”.
