SOLUTION: This printing system consists of a printer 6 that includes a printer controlling section 7, a consumable article 10, memory means 8, 9, 11 and a network communication means and accumulates printing history information into the memory means at each time of printing data, and a host computer 1 connected to the printer 6. The host computer 1 comprises a network communication means, a managing means 4 for managing a date such as a replaced date of the consumable article 10, a means for reading the printing history information from the printer 6, a means 3 for predicting a date to replace the article based on the printing history information read from the printer 6 and an indicating means 2 for indicating the predicted result of each consumable article. An interval for monitoring the printing information accumulated in the printer can be varied from the host computer. |
