Abstract: A droplet discharge apparatus includes a plurality of dischargers and a control device. The plurality of dischargers discharge droplets. The control device acquires characteristic values of end portions of areas on which the droplets discharged by the plurality of dischargers land, from a measurement of the end portions. The control device adjusts the plurality of dischargers such that a difference between the characteristic values is within a range.

Abstract: Techniques for handling and reducing ink overspray of an ink jet printer are provided. In an example, an ink overspray collector for an ink jet printer can include a first opening defining a first print area of the ink jet printer, and a frame about the first opening. The frame is configured to receive overspray from operation of the ink jet printer and can be formed of a woven material. In some examples, a controller of the ink jet printer can reduce an amount of ink ejected near the edges of the print media to reduce overspray.
