A method and system for predicting ink usage during a print job for an ink jet printer and displaying information in connection with ink usage on a system monitor. The method steps include determining the initial ink level of an ink cartridge and developing a histogram of ink usage associated with a threshold number of items to be printed. The threshold number is less than the total number of items to be printed and should be an amount representative of each of the print items. The usage associated with the threshold number, i.e., the histogram, may then be extrapolated to evaluate the number of items which can be printed before the ink cartridge is depleted. The number of items which can be printed is then displayed to the user/operator on a system monitor so that a determination can be made concerning whether the print job may be completed. Additionally, the time remaining and/or the ink cartridge to be depleted first can be displayed to provide additional information to the operator concerning the replacement/replenishment of ink cartridges.
