Abstract: The present invention involves a pneumatic card handling unit accommodating a cartridge with a plurality of cards therein having information in the form of coded perforations that are pneumatically sensed. The unit includes means operable during successive cycles to withdraw individual cards in succession from the cartridge, read the information, and return the cards to the cartridge. A printing means such as ''''Selectric'''' typewriter (IBM registered trademark) is interconnected by a pneumatic cable with the card reading unit for printing of information automatically under control of the card unit. The system further includes means for controlling tabulation functions of the printer according to diverse program cards during the printing process. Also, interlock means are provided to insure completion of operations requiring a relatively longer period of time, such as carriage return and tabulation.

Abstract: A single-elment printer having a complex drive cam for control of print impact velocity, employs power taken from the print shaft within the type element carrier to perform backspace operations as selected by the velocity control mechanism.
