Hochqualitativer Strahldrucker und Verfahren

A printer suitable for colour and monochrome printing which uses an ink jet printhead 16 in which the marking fluid contains no dye so that a latent image of the desired print pattern is produced in the form of moistened spots directly on the print medium 12 as it passes through a print station 15. The latent image is then subsequently developed at a developing station 18 where coloured powder is applied to the fluid latent image. The developed image is then fixed at a fixing station 19 to produce a visible and permanent image of the desired print pattern on the medium. By using several developers 40 at the developing station each with a different colour powder, multicolour images can be printed by feeding the medium through the printer in successive print cycles.
