摘要： 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.

摘要： The thermal printer includes a thermal recording head and a platen roller. The thermal recording head records the image on a thermal recording material by contacting therewith at a predetermined pressure. The platen roller is arranged to face the thermal recording head and supports and transports the thermal recording material to be recorded thereon. The platen roller is covered with covering rubber in which the relation between hardness H (degree) and thickness t (mm) satisfies the following formula: 5t+30≦H≦5t+50. The thermal printer is capable of obtaining a recorded image of high-quality without generating unevenness of an image, unevenness derived from a streak, a blur or the like.
摘要翻译：热敏打印机包括热敏记录头和压纸辊。热敏记录头通过与预定压力的接触将图像记录在热敏记录材料上。压辊布置成面对热敏记录头，并支撑并传送待记录的热敏记录材料。压辊用覆盖橡胶覆盖，硬度H（度）和厚度t（mm）之间的关系满足下式：5t + 30 <= H <= 5t + 50。热敏打印机能够获得高质量的记录图像，而不产生图像的不均匀性，从条纹导致的不均匀性，模糊等。
