Abstract: Operation commands, each corresponding to an input operation through an input unit, are linked together. Thereby, a single operation command string is generated from a sequence of input operations and the thus generated operation command string is recorded on a command record buffer. The recorded operation command string is converted into two dimensional bar code data and printed. The operation command string is read out from a two dimensional bar code by a bar code scanner. The operation command string thus read out is executed by a CPU etc.

Abstract: A droplet discharge device includes a droplet discharge head, a feed reel, a drying chamber, a drying-gas-introducing device, a take-up reel, an imaging device, an analyzing unit and a control unit. The imaging device captures an image of functional liquid discharged from nozzles of the droplet discharge head onto a sheet member between the feed reel and the take-up reel with the sheet member having been dried in the drying chamber filled with a drying gas to achieve a predetermined humidity. The analyzing unit measures an area over which the functional liquid is deposited on the sheet member from each of the nozzles, and calculates a distribution of a discharge amount of the functional liquid. The control unit adjusts a voltage applied to the drive elements so that the discharge amount of the functional liquid from each of the nozzles approximates a predetermined optimum amount.

Abstract: In a 2M-pass printing operation that forms dots including overlapping dots, this invention makes an arrangement to ensure that the number of overlapping dots that are printed in a unit area in pairs of passes each straddling a print medium convey operation executed between an Mth pass and an (M+1)st pass is greater than the number of overlapping dots that are printed in pairs of passes straddling any other convey operation. This arrangement can cause two dots of the overlapping dots to be separated from each other in the event of a print position misalignment, preventing a possible density fall even in a unit area where the largest density reduction is feared to occur at time of the print position misalignment.
