A computer system for automatically ordering consumables for a printer or a similar machine where the inventory is monitored by comparing the amount of material delivered, for example, by scanning the incoming cartons, against the amount used, for example, by the machine automatically sending to the computer counts of the various units consumed. The computer is equipped with a set of rules for automatically reordering new supplies. In an alternative case, the rules would request a concession, in terms of price or some other parameter such as quantity, from one or more vendors before ordering.
