Each of the 120 print positions had a print hammer which when fired squeezed the paper and an inked ribbon between itself and the rotating print barrel for a fraction of a second. It is reputed to be the first commercially produced barrel printer.

Famous quotes containing the word standard:
“I don’t have any problem with a reporter or a news person who says the President is uninformed on this issue or that issue. I don’t think any of us would challenge that. I do have a problem with the singular focus on this, as if that’s the only standard by which we ought to judge a president. What we learned in the last administration was how little having an encyclopedic grasp of all the facts has to do with governing.”
—David R. Gergen (b. 1942)
