Abstract
A method is disclosed. The method includes setting a desired flow rate for ink in an ink jet printer, measuring an actual flow rate of the ink, determining if the measured flow rate is equal to the desired flow rate and adjusting the flow rate if the measured flow rate is not equal to the desired flow rate.

A printer comprising:
- a print engine including:
- an ink jet print head having a plurality of ink nozzles;
- and
- a cartridge to supply ink to the print head;
- and
- a control unit to compare a measured flow rate to a desired flow rate to regulate ink flow from the cartridge to the print head, and to adjust the flow rate if the measured flow rate is not equal to the desired flow rate.
