4631

The Tektronix 4631 Video Hard Copy Unit is a printer for CRT storage displays, e.g., the 613, or 4010-series terminals.

Using a special "1-dimensional", magnetically deflected CRT, it exposes dry silver paper (3M type 777, shelf life 6 months only). The image is developed by heating the paper. Print time is 18 seconds except for high-res copies from 19" terminals, for which it can be doubled.
