规定了读卡器打印机的基本性能特征，读卡器打印机设计用于查看和制作最大宽度为35 mm的缩微胶片的硬拷贝，无论是以缩微胶片条或卷的形式，还是以开卷、盒式或盒式、缩微胶片、夹套和图像卡的形式。根据ISO 1号和ISO 2号微测试图表的使用，或从规定最低质量的缩微胶片（原件或副本）中，为读卡器打印机生成的硬拷贝打印确定最低标准。 适用于放大率小于或等于50:1的读卡器打印机。

Specifies the essential performance characteristics of reader-printers designed for viewing and making hard copies from microfilm with a maximum width of 35 mm, whether in microfilm strips or in roll form, in open reels, cartridges or cassettes, microfiches, jackets and image cards. Establishes minimum criteria for the hard copy prints produced by reader-printers based on the use of microtest charts ISO No. 1 and ISO No. 2 or from microforms with a specified minimum quality, either an original or a duplicate. Applies to reader-printers with a magnification less than or equal to 50:1.
