Handheld dot printing device

摘要

A portable dot printing device including an encoder for detecting movement amount of the portable dot printing device across the recording medium and for producing a pulse signal based on a minimum movement amount detectable by the encoder; and a print head formed with at least a first element row and a second element row each having elements for printing dots on the recording medium, the first element row and the second element row being separated by a predetermined pitch equal to a multiple of the minimum movement amount, the print head being controlled to print images using the elements based on the pulse signal from the encoder.
