Abstract
A magnetic print module for use as a printhead of a magnetic printing system. The print module comprises a base having a matrix of integral protrusions extending upward from the base and a plurality of coils wrapped around the base between the rows and columns of the matrix. By selectively energizing four coils at a time, a current path may be formed around one of the protrusions, which induces a magnetic field in the protrusion and permits it to print a dot in a recording medium. In order to form a printhead with minimal spacing between print positions, a matrix having a plurality of print rows may be formed and the matrix skewed with respect to the path of the recording medium.
