This mechanial printer was used each day to transmit the day's mission plan, called an "Execute Package," from controllers at NASA's Manned Spaceflight Center in Houston to the crew of the Space Shuttle. It is a mechanical, line-at-a-time printer. Although eventually replaced by a thermal printer system, it continuted to be used as a back up.
This teleprinter was installed in the Columbia and flown on several missions, including STS-32, 40, 50, and 55. It was also flown on other Shuttle missions until about 1996.
NASA transferred this printer to the Smithsonian in 1996.
