In 1877 industrial printer Edward Arnott Clowes, grandson of machine printing pioneer William Clowes, published a lengthy paper entitled "Printing Machinery" in the Minutes of Proceedings of the Institution of Civil Engineers, Vol. 89, 242-284 This paper provided the best analysis that I have seen of the developments that had occurred in printing machines since their invention by Friedrich Koenig up to the time of writing. At the end of his paper Clowes provided four tables:
Table I: Speed
Table II: Processes involved in Printing a Single Side of a Sheet of Paper
Table III: Chronological Synopsis
I. Single Machines, printing one side only.
III. Platen Machines
IV. Rotary Machines
In addition to this "insider" analysis, the "Discussion" of Mr. Clowes' paper that was published after it included the comments of numerous other figures significant in the development of the technology including, Julian Hill, nephew of Sir Rowland Hill, J. Murdoch Napier, son of David Napier, William Blades, and E. A. Cowper, son of Edward Cowper.
