Abstract
A printer according to this invention includes a print head, a carriage, a recovery unit, and a controller. The controller causes a recovery operation to be performed based on a total value of two values. Assuming that front and rear arrays of discharge port arrays during outbound movement of the carriage are defined as first and second arrays, respectively, the first value is obtained by multiplying a sum of an amount of ink discharged from the first array during outbound movement of the carriage and an amount of ink discharged from the second array during homebound movement of the carriage by a first coefficient, and the second value is obtained by multiplying a sum of an amount of ink discharged from the second array during outbound movement of the carriage and an amount of ink discharged from the first array during homebound movement of the carriage by a second coefficient.
