Abstract: A jetting assembly for ejecting a print material includes an actuator for applying a pressure to the print material, and further includes jetting assembly block that defines a pump chamber, a converging part (i.e., a narrowing taper), and a nozzle bore that ends or terminates in a nozzle from which a drop of the print material is ejected. An implementation can further include a throat and a diverging part that, together with the converging part, forms a venturi. The converging part results in an increase in a velocity of the print material and a decrease in pressure as the print material passes an supply port of a supply channel. The decrease in pressure can result in a replacement of at least a portion of the drop volume within the throat or the nozzle bore even before the drop is ejected from the nozzle.

Abstract: A print engine performs printing on a print medium conveyed by a conveyor. The cutter cuts the print medium conveyed by the conveyor. The first sensor is provided upstream of the cutter in the conveyance direction and detects a leading end and a trailing end of the print medium. The second sensor detects a conveyance amount of the print medium conveyed by the conveyor. The controller determines a print medium length that is a length of the print medium in the conveyance direction, based on the conveyance amount detected by the second sensor from when the first sensor detects the leading end of the print medium until when the first sensor detects the trailing end of the print medium, determines a cutting position of the print medium based on the determined print medium length, and controls the cutter to cut the print medium at the determined cutting positon.

Abstract: A pressureless high-frequency suspension thermal transfer printer is disclosed, in which a high-frequency signal of 60-100 Hz is generated by a high-frequency switching power supply, and a high-frequency energy conversion motor is driven to convert a signal into high-frequency mechanical vibration which produces 60-100 Hz high-frequency waves which propagate in a longitudinally diffused manner in which an entire transfer printing surface is covered in a direction that is perpendicular to the transfer printing surface, avoiding wasteful loss in the direction of lateral propagation parallel to the transfer printing surface, so that the high-frequency waves act on a molecular movement during the transfer printing process to the greatest extent, which effectively changes a state of the molecular movement, enhances a molecular penetration force, realizes replacement of physical pressure with the high-frequency waves, completely changes a thermal transfer printing process, and achieves pressureless thermal transfer
