A droplet discharging head executes multi-path recording in which dot recording in one main scanning line is completed by n main scans when n is an integer of 2 or more. The droplet discharging head includes: a plurality of nozzles configured to discharge a liquid as droplets; a pressure chamber defining substrate defining a pressure chamber communicating with the nozzles; a piezoelectric element including a first electrode, a second electrode, and a piezoelectric layer containing a perovskite-type composite oxide containing K, Na, and Nb as a main component; and a vibration plate forming a part of a wall surface of the pressure chamber and configured to vibrate by driving of the piezoelectric element. The number of paths n in the multi-path recording, a piezoelectric constant d[m/v] of the piezoelectric element, and a ratio x of a Na molar fraction to a total value of a K molar fraction and the Na molar fraction in the piezoelectric layer satisfy a relationship represented by a formula (1).

Droplet discharge head and droplet discharge apparatus

An interface, to which a recording medium storing at least one first setting information item is removably attached to a printer. A storage stores hardware specification data. A reader reads out the at least one first setting information item from the recording medium attached to the interface. A register judges whether the at least one read out first setting information item matches with the hardware specification data, and registers the first setting information item which matches with the hardware specification data as at least one second setting information item. A selector selects one of the at least one second setting information item as a print condition.

Printer and print-condition setting method for the same

Provided is a printing device for preparing print data from image data and sequentially printing the print data, the printing device including: a print instruction receiving unit which receives a print instruction with the selection of the image data; and a print data preparing unit which, when the print instruction is received by the print instruction receiving unit with the selection of a plurality of pieces of image data including JPEG data and RAW data before a development process, performs a process of preparing the print data from the JPEG data among the plurality of pieces of selected image data prior to a process for performing the development process with respect to the RAW data and preparing the print data if at least a predetermined amount of print data in a print standby state, in which printing is not completed by the printing device, is not present, and performs the process for performing the development process with respect to the RAW data and preparing the print data prior to the process of preparing the print data from the JPEG data if the at least predetermined amount of print data in the print standby state, in which printing is not completed by the printing device, is present.

Printing device that prioritizes processing of raw and JPEG data according to amount of print data in standby state

A print medium of the present invention has a structure in which a substratehas an extending portionextending from the portion fixed to a lenticular sheetto the right in the drawing and adjacent to the rectangular lenticular sheet. Printing 'parallactic images', 'an addressee', and &#x201c;a fold&#x201d; on an ink permeating layer, a print paper, and the ink permeating layerof the print medium, respectively, and folding the extending portionwith respect to the &#x201c;fold&#x201d; facilitates bonding the portion on which the addressee is printed to the back surface of the lenticular sheet
