Abstract:
1. A printer, comprising: a head, which ejects a liquid; a liquid cartridge, which includes: a writing/reading portion, which reads the first and second thresholds, the liquid amount information and the waste liquid amount information from the storage portion; and a determinant, which judges both whether a liquid amount of the liquid amount information read from the storage portion reaches the first threshold and whether a waste liquid amount of the waste liquid amount information read from the storage portion reaches the second threshold; and a notifier, which notifies a life time of the liquid cartridge when either one of the two judgments is judged by the determinant, wherein the first threshold indicates a near liquid end state in which the liquid in the first housing portion is near to end; wherein the second threshold indicates a near full state in which the waste liquid in the second housing portion is near to full; wherein the liquid amount information indicates the liquid amount of the liquid contained in the first housing portion; wherein the waste liquid amount information indicates the waste liquid amount of the waste liquid contained in the second housing portion; and wherein the ink cartridge and the waste liquid cartridge are integrally formed.
