Answer
A bent or broken pin within the printhead assembly
In a dot-matrix impact printer, the printhead contains a matrix of small metal pins that strike an inked ribbon to form text and images on paper. When one pin is broken or stuck inside the printhead assembly, it leaves a continuous horizontal white blank space through every line of printed text.
