ABSTRACT:
The present invention is concerned with the control of the format of documents, such as letters, prepared automatically on a printer in response to code signals read from a record medium (magnetic storage medium), and to mode control means for associated apparatus. The invention concerns itself particularly with the handling of left margins and indentation levels for different paragraphs in a document especially when a document under preparation has line lengths that are either shorter or longer than the line lengths of an original document that was prepared concurrently with the storage of the coded signals on the record media. A preferred embodiment includes an input/output printer having a keyboard for entry of information and a single element print head for printing of information and an associated unit including an associated recorder for recording key entries as code signals on a magnetic tape record medium and an associated reader for subsequently reproducing the code signals for printing. Counter means are provided for controlling identation levels during playback of information from a magnetic tape. In a first version, the single element print head is returned all the way to the left margin and tab operations are performed to bring the print head to the beginning of the line for the individual paragraphs.
Provision is made for reading format, character, and functional code signals on a source media according to one indentation format, translating and printing characters according to another indentation format, and recording another media in accordance with the printer action by performing code conversion of signals.
