A swath printer and multipass printing method for improving print quality. The printer minimizes dot placement errors on a printed medium due to depositing drops of ink from lower quality printhead nozzles by providing a printmask having a mask pattern which prints with those nozzles most susceptible to dot placement error using a hi-fipe printmode which deposits into a specific pixel location a small number of drops in each of multiple passes, and a multidrop printmode which deposits into a specific pixel location many drops rapidly in one of the passes. Because such a printer and method prints substantially equally with all printhead nozzles, it does not shorten the useful life of the printhead due to defects associated with the number of times a nozzle deposits ink.
