The [[IBM]] '''Electromatic Table Printing Machine''' was a typesetting-quality printer, consisting of a modified [[IBM Electromatic typewriter|IBM Electromatic Proportional Spacing Typewriter]] connected to a modified [[IBM 016]] keypunch. A [[plugboard]] control panel was used for programming and formatting of the printout.<br />
<br />
A deck of [[punched card]]s containing the table (calculated and punched by other [[unit record equipment]]) to be printed was put into the IBM 016, which read them and then controlled the typing of the typewriter through a box containing [[solenoids]] that depressed the keys. Printed output could then be photographically reproduced on a [[printing plate]], which would be used in a [[printing press]] to make as many copies as needed.<ref name="Smart card alliance">{{cite web|url=http://www.smartcardalliance.org/pages/publications-emergency-response-official-credentials|title=Emergency Response Official Credentials: An Approach to Attain Trust in Credentials across Multiple Jurisdictions for Disaster Response and Recovery|date=January 3, 2011|access-date=July 13, 2017|archive-date=January 27, 2013|archive-url=https://web.archive.org/web/20130127012958/http://www.smartcardalliance.org/pages/publications-emergency-response-official-credentials|url-status=dead}}</ref><ref name="http://www.simalliance.org/en?t=/documentManager/sfdoc.file.supply&fileID=1279268442341">{{cite web | url=http://www.simalliance.org/en?t=/documentManager/sfdoc.file.supply&fileID=1279268442341 | title=Update from SIMalliance on SCWS | date=30 June 2010 | accessdate=March 20, 2012 | author=Martin, Christophe | archive-date=1 August 2013 | archive-url=https://web.archive.org/web/20130801073734/http://www.simalliance.org/en?t=/documentManager/sfdoc.file.supply&fileID=1279268442341 | url-status=dead }}</ref><br />

[[Columbia University]] Astronomy Professor [[Wallace Eckert]] was examining the process used by the Navy to produce Air Almanacs. Deciding that the manual computation techniques used were too slow and error prone, he recommended automating the process with existing punched card based unit record equipment. One of the hardest problems was getting a high-quality printout of the tables. Initially [[IBM 405]] accounting machines with special modifications were used, but he wanted something better. In 1941 Eckert developed a specification for a card-driven composing typewriter and asked IBM to design and build it.{{citation needed|date=July 2017}}<br />
<br />
The first Electromatic Table Printing Machine was delivered to him in 1945. It produced it first Air Almanac in 1946.{{citation needed|date=July 2017}}<br />
