The invention relates to a method for printing on a substrate by means of inkjet printing, in which method landing zones are provided on the substrate in a landing zone grid consisting of landing zone columns and landing zone rows, and the landing zones are each printed on using an individual pattern consisting of one or more drops by means of one or more print head nozzles of a print head, wherein the print head nozzles are moved over a surface of the substrate along an imaginary nozzle path during printing. The invention also relates to a device for printing on a substrate comprising a landing zone grid consisting of landing zone columns and landing zone rows by means of inkjet printing. In order to provide a method and a device for printing on a substrate by means of inkjet printing, which method and device allow a substrate to be printed on efficiently and simply, with the print result being particularly uniform and without unwanted artefacts and in particular the printed surface being free from lines and Moir effects, in the method landing zones are provided on the substrate in a landing zone grid consisting of landing zone columns and landing zone rows, and the landing zones are each printed on using an individual pattern consisting of drops by means of print head nozzles of a print head, wherein the print head nozzles and the surface of the substrate are moved relative to one another along an imaginary nozzle path during printing. All individual patterns of a print nozzle path are printed in multiple passes, wherein in each pass only parts of individual patterns and/or only some of all individual patterns are printed along the nozzle path in landing zones, and in at least one subsequent pass missing parts of individual patterns or further entire individual patterns are printed in incomplete or empty landing zones. In addition, between the individual passes, the print head and the surface of the substrate are moved relative to one another laterally to the nozzle path by a lateral offset.

A display arrangement for e.g. a medical substance delivery device includes a movable control member, at least one transducer responsive to movement of the control member to convert mechanical energy into electrical energy to output an electrical signal, a drive circuit for receiving the electrical signal and for outputting an output drive signal, and a display device for receiving the output drive signal and displaying a variable image that varies consequent on the relative movement. The display may be a bistable display, so that the display function is self-powered without a requirement for a battery or the like. The parameter displayed for a medical substance delivery device may be a dose volume, a count of doses delivered, progress and/or completion of a dose. The drive circuit is an absolute position encoder and detects the actual position of the control member and does not deduce the position by counting pulses.
