[Object] To appropriately warm ink.

[Solving Means] An inkjet printer 1 includes an inkjet head 3 and an ink warming mechanism 12. The ink warming mechanism 12 includes a warming part main body 21; an ink flow path 21a formed inside the warming part main body 21; a heater 22 that is attached to the warming part main body 21 and heats the warming part main body 21; a warming part temperature sensor 23 that is attached to the warming part main body 21 and detects a temperature of the warming part main body 21; and a heater controller 4 that controls the heater 22. The heater controller 24 controls the heater 22 based on the detection result of the warming part temperature sensor 23 so that the temperature of the warming part main body 21 becomes a predetermined reference temperature.

A liquid ejecting apparatus includes a printing portion and a control portion. The printing portion executes a printing operation including ejecting a liquid from a nozzle onto a medium. The control portion executes an initial operation upon supply of power and executes the printing operation in accordance with a print instruction. The initial operation and the printing operation include a common printing operation that is common to the initial operation and the printing operation. When the control portion does not receive the print instruction during execution of the initial operation, the control portion executes the initial operation including the common printing operation. When the control portion receives the print instruction during execution of the initial operation, the control portion omits the common printing operation from the initial operation.

An aerosol jet printer producing a stream of droplets in a print jet employs direct, droplet-resolving imaging to characterize the statistics of the droplets in flight for improved control of the printed line characteristics.

A system comprises a printhead including a nozzle, a temperature sensor and a processor. The temperature sensor detects the temperature of a location of a print surface upon firing the nozzle to eject a drop of printing fluid to the location of the print surface. The processor determines whether the nozzle ejected the drop properly using the detected temperature.
