Olivetti ET121, nylonová barvicí tape do psacího stroje

The Olivetti ET121 nylon ribbon is impregnated with coloring ink. The advantage of this tape is that it lasts a long time because the tape rewinds continuously. Unfortunately, the print quality – sharpness – is noticeably worse than with the carbon ribbon. The ribbon should be replaced when the print starts to fade and becomes harder to read.
