'''Comb printers''', also called [[line matrix printer]]s, printed a matrix of dots instead of individual characters in the same way as single-character dot matrix printers, but using a comb of hammers to print a portion of an entire row of pixels at one time (for example, every eighth pixel). By oscillating the comb or "print shuttle" left and right a short distance, the entire pixel row could be printed (continuing the example, in eight cycles). The paper then advanced and the next pixel row was printed. Because far less print head motion was involved than in a conventional dot matrix printer, these printers were much faster, and competitive in speed with formed-character line printers without being restricted to a set of available characters, thus being able to print dot-matrix graphics and variable-sized characters.

[[Printronix]] and [[TallyGenicom]] are well-known vendors of comb printers. In 2009, TallyGenicom was acquired by Printronix.
