Abstract
A multipass printing method includes determining at the end of a printing pass if at least some dot depositing elements of at least one printhead require a servicing operation. In case the determination is positive, the method includes printing at least one incomplete printing pass in which at least the dot depositing elements of the at least one printhead that require a servicing operation are not operated to print. At the end of the incomplete printing pass, the method includes servicing at least the dot depositing elements of the at least one printhead and printing at least one compensating printing pass, which adds to the information to be printed in the compensating printing pass at least part of the information that failed to be printed by the dot depositing elements of the at least one printhead in the at least one incomplete printing pass.
