Abstract: The liquid ejecting apparatus is adapted to eject a waste ink from a liquid ejecting head, the waste ink H comprising color inks C, M, Y, K that have been discharged from a nozzle in a recovery operation serving to recover an ejection function of the nozzle. The apparatus includes a control device configured to use a conversion table determined based on quantity ratios of the color inks C, M, Y, and K making up the waste ink to convert image data into ejection data indicating quantities of the color inks C, M, Y, and K and the waste ink that should be ejected from the liquid ejecting head.

Abstract: A serial printing device that has a wider printing region without elongating the platen shaft. The serial printing device includes a serial printing head (7, 8) mounted on a carriage, a medium feed control device (23), a carriage control device (24), and a data discriminating device (21). The serial printing head includes a plural number of dot forming element series each having a plural number of dot forming elements linearly arrayed in a printing medium feeding direction. The dot forming element series are arrayed in a printing medium width direction. The medium feed control device controls a first printing process wherein, when the carriage is accelerated and moved from a home position at a constant speed for printing, print data is outputted to the serial printing head to print an image of one line by one printing path.
