Borderless inkjet printing, using continuous airstream to collect ink drops released slightly beyond edges of print medium

A borderless inkjet printer includes a printhead movable to release ink drops on a print medium, and to release ink drops slightly beyond edges of the print medium in order to ensure edge-to-edge printing on the print medium. A air flow generator generates a constant airstream with direction and force so that ink drops released slightly beyond edges of the print medium are carried away by the constant airstream to prevent the drops from clinging to any edge of the print medium or even migrating to an underside of the print medium. A sump collects inkdrops carried by the constant airstream, to permit them to be reused for printing.
