ABSTRACT:
An unattended printing system in which the operator keys in a page line count defining the number of lines to be printed on a page from codes derived from a shift register memory which is automatically loaded from a pack feed magnetic read/recorder. Logic is provided which, in the event that the text being played out does not equal a full page, automatic indexes or carrier returns will be generated to cause the page to be fed such that the printing mechanism is then in alignment with the first line of the next page. While page feeding occurs the memory is also automatically cleared; a new card is fed and reading of new codes into the shift register initiated. In addition, in the event that the margins on the machine which is being used for playout differ from the margins which were used during source recording, in the event that a fewer number of lines of text result, the proper number of indexes for this fewer number of lines to cause proper alignment on the next page will be output. Further, in the event that the margins are changed such that the lines being printed out on the printer are shorter than those originally recorded, proper indexing for this greater number of lines to place the following page in proper alignment will be output provided that the total lines of text output do not exceed the page count entered. In the normal case line endings will have been determined and the margins will not be changed to prevent possible systems stoppage for hyphenation decisions.
