Abstract
A line printer with a hammerbank having print hammers with printing tips and a ribbon supported for impact by the tips for printing on media and a metal platen for supporting the media. An elastomer on the metal platen supports the media and has a layer of material harder than the elastomer extending inwardly from its surface which receives the impacts of the hammer tips. The harder material can be particles extending inwardly randomly from the surface of the elastomer of a ceramic having a sphericity exceeding 0.50 up to 35 percent of the thickness of the elastomer, and in the range of 20 microns to 400 microns in size.
