Abstract
A matrix printer is furnished with a matrix print head (1) supported on a back and forth movable slider (2), guided on a rail guide (3), wherein the print elements (4) can be operated at a high frequency. A matrix print head (1), disposed fixedly in its position relative to the slider (2), is furnished at least at one reference face (8) between the matrix print head (1) and the slider (2) with a sound-insulating layer (10) of an elastic material, and where the matrix print head (1) and the slider (2) can be braced and/or clamped to each other in this region. This construction opposes a sound formation and sound propagation via the print head, the slider (2) and the rail guide (3) by body sound conduction onto frame parts of the printer by employing sound-insulation and sound absorption.
