PROBLEM TO BE SOLVED: To reduce the down time of an apparatus requiring expendables by making it possible to prepare expendables previously before supplement of expendables is required. SOLUTION: An expendables management server 6 receives data of the extent of consumption of expendables (expendable information) from each printer 2, 2,... through a network 3 and stores the data in a printer information DB 51. Record data of the expendable information is then read out from the printer information DB 51 and the time remaining before supplement of expendables is required (duration of expendables) is predicted for each printer 2, 2,.... Quantity of expendables required to be supplemented can thereby be determined respectively every unit time for the entire printers 2, 2,.... |
