The X9700 could print on regular 8½×11 paper in traditional monospace "ASCII typewriter font" (like a line printer, or like its predecessor, the Xerox 1200) but also in proportionally spaced Helvetica with effects like boldface, italics, and font-size changes, box-drawing, etc, and so (for example) it could print a manual like THIS ONE that was prepared using the Scribe document preparation system[5]. The X9700 and Scribe ushered in the era of "rich text" and do-it-yourself typesetting at Columbia.
Users of the DECSYSTEM-20 and IBM mainframes would queue their jobs for printing, which were written to magnetic tapes throughout the day. In the evening, machine-room operators would bring the tapes to Watson, run the jobs on the 9700, and then carry the output (and tapes) back to campus for distribution the next day. After about ten years the 9700 was moved to the main machine room on campus where it served for probably another ten years, and even after that Columbia continued to offer X9700 printing through an external service.
The control terminal is a Lear Siegler ADM ADM-3A[4].
