Abstract
An improved ribbon cassette is provided for a receipt printer of the impact printing type. The ribbon cassette has two raised areas disposed on the distal ends of the ribbon presenting arms, about the print area defining the ribbon window. These raised areas act as pressure bumps or spring-like retaining pads that bias the paper against the platen. In accomplishing the bias, a paper bubble commonly formed in the ribbon window area is substantially reduced or eliminated. This has the effect of reducing the noise generated by the impact wires of the print head striking the paper.
