A system for performing substrateless and/or local donor Laser Induced Forward Transfer (LIFT), comprising a reservoir (9) comprising at least one opening and an energy source configured to deliver energy to a donor material within said reservoir, characterized by at least one of: said reservoir is embedded into a medical device; said reservoir is in fluid connection with a medical device; said reservoir is incorporated into a medical device; said reservoir contains at least one biologically active substance; and, said reservoir is in fluid connection with at least one source of at least one biologically active substance. This system enables deposition of material by LIFT without any need for a donor substrate. Methods of substrateless and local donor LIFT, in particular for medical and biological applications, are also disclosed.

A liquid ejection head in the present disclosure includes a first channel member and a second channel member. The first channel member includes a first surface, a plurality of ejection ports in the first surface, a second surface on the opposite side to the first surface, a third channel, a plurality of pressurizing in communication with the third channel and with the plurality of ejection ports respectively, and a fourth channel. The second channel member is on the second surface and includes a first channel in communication with the third channel and configured using resin and a second channel in communication with the third channel through the forth channel.

A system for performing substrateless and/or local donor Laser Induced Forward Transfer (LIFT), comprising a reservoir (9) comprising at least one opening; and an energy source configured to deliver energy to a donor material within said reservoir. In preferred embodiments of the invention, the energy source is a pulsed laser. This system enables deposition of material by LIFT without any need for a donor substrate. Methods of substrateless and local donor LIFT are also disclosed.

There is provided a controller for an image recording device. The image recording device includes: a carriage capable of moving in a first direction; a head mounted on the carriage and configured to discharge a liquid from a nozzle; and a wiper capable of being impregnated with a cleaning liquid, a nozzle surface of the head including a first region not having the nozzle and a second region having the nozzle. The controller is configured to execute: a pressing-against processing of abutting the wiper on the first region in a state in which a speed of a relative movement in the first direction between the carriage and the wiper is a first speed; and a moving processing of moving the carriage and the wiper relative to each other in the first direction at a second speed faster than the first speed, while abutting the wiper on the second region.
