ABSTRACT:
A mosaic printing head for use in a computer printer includes a needle guiding assembly and an electromagnet assembly for activating the needles. The printer head utilizes a unique design to provide for simple and fast adjustment of the position of each printing needle while eliminating any effect on the adjustment because of vibrations occurring during the printing. This design allows the needle stroke to be adjusted so as to achieve very high speed printing operation.
