    • A device for monitoring the supply of printing liquid in the reservoir of an ink-operated printer and the like, in which two monitoring electrodes are disposed in and wetted by the printing liquid, with circuit means being connected to the electrodes for monitoring the electrical resistance therebetween, which resistance varies in response to changes in the amount of ink in the reservoir. Means are provided, responsive to predetermined resistance values, for actuating at least one display element, and/or effecting disconnection of an associated printer. Additional circuit means may also be connected to the monitoring means for actuating a preliminary warning device prior to actual triggering of a display element indicating the exhaustion of the printing liquid supply. Means also may be provided for monitoring the supply of a data carrier, i.e. paper, which means may likewise be operatively connected to the display element, whereby the latter serves as a common display element to indicate both the operational status of the ink supply reservoir and the presence of a data carrier for receiving the printing.

    • A printer includes a printer carrier having a surface for receiving ink for transfer printing onto a carrier material, such as paper. Areas of the surface print carrier are ink attracting and others are made ink repelling. The ink repelling areas are formed by providing the surface with a layer of a substance in a solid phase, such as water in the form of ice. The ice layer repels the ink as it is applied so that the ink is only held on the surface of the print carrier at the areas that are ice free. The ice layer is formed by cooling the surface using a cooling mechanism to form a coating of frost due to condensation. A surface tension reducer for water is coated on the surface prior to cooling the surface. A laser or other radiation emitter structures the ice layer to form the print image.
    • 打印机包括具有用于接收用于将纸张转印到载体材料上的油墨的表面的打印机托架。 表面印刷载体的区域是吸墨材料,而其它部分被制成墨水排斥。 通过为表面提供一层固体物质,例如冰形式的水来形成防油墨区域。 在施加墨水时,冰层排斥墨水,使得墨水仅在无冰的区域上保持在印刷载体的表面上。 冰层通过使用冷却机构冷却表面而形成,以形成由于冷凝而产生的霜的涂层。 在冷却表面之前,将表面张力减小剂涂覆在表面上。 激光器或其他辐射发射器构造冰层以形成打印图像。

    • Disclosed is a piezo bending transducer drop-on-demand print head and a method of actuating it. Each of the piezo bending transducers of a piezo bending transducer drop-on-demand print head is subjected to a sequence, corresponding to the desired print image, of triggering pulses each effecting a drop discharge movement and, assigned to each triggering pulse, each piezo bending transducer neighboring the piezo bending transducer triggered by the triggering pulse is subjected to a compensating pulse deflecting it. The piezo bending transducer drop-on-demand print head has a nozzle plate with nozzles arranged in series. Respectively assigned to each nozzle is a piezo bending transducer which can be subjected to a triggering pulse accompanied by a drop being discharged from the respective nozzle. There is a control device by which each of the piezo bending transducers can be subjected to triggering pulses and compensating pulses in accordance with the method of the invention.

    • An ink writing head comprising ink ejection channels and piezoelectric transducer elements allocated to the ink ejection channels, these transducer elements being supplied with writing fluid via supply lines, contains transducer elements comprising a first piezoelectrically excitable layer and a supporting layer firmly joined to the excitable layer. The piezoelectrically excitable layer comprises deflectable regions that are respectively subdivided into a peripheral and into a central region. For generating the needed excursion of the membrane, the regions of the membrane are driven such that the peripheral region is shortened, preferably by transversal contraction, and the central region is lengthened.
