Near letter quality (NLQ) characters are formed using direct electrostatic printing (DEP) by providing a printhead structure containing at least three equally spaced rows of equally spaced and staggered apertures. In the preferred embodiment, the printhead structure includes at least four rows of apertures. The number of rows is equal to the disance between aperture centers divided by the diameter of a spot of toner deposited by each of the apertures. |
