发明名称 Impact printer type character
摘要 A type surface useful in an impact printer having type characters thereon particularly configured to print large solid blocks. Each type character is comprised of a plurality of spaced land area portions distributed in an area of the type surface whose periphery conforms to the shape and size of the solid block to be printed. The plurality of land area portions present a lower effective contact area to an impacting hammer than would a solid land area of the same periphery, therefore yielding higher density print. The spaces between the land area portions fill in on the printed character as a consequence of smear attributable to the relative movement between the type surface and ink ribbon.
