Abstract: PRINT MEDIUM SOURCE SELECTION In an output printer for use in word processing or data processing applications an apparatus for handling a plurality of document types such as continuous forms and cut sheets is provided. In the present invention there is disclosed a user-friendly technique comprising interactive sequences of operator actions and hardware condition detection by the control logic for selecting the document type handling apparatus for a given print session.

Abstract: AT9-?1-001 WORD PROCESSING SYSTEM HAVING A FORMATTING BIDIRECTIONAL PRINTER A word processing system is provided having a bidirectional printer with formatting capability. The system includes a word processor having means for outputting a stream of sequential data readable in only one direction. The data comprises blocks of character data representative of the characters to be printed interspersed with blocks of control data representative of the format in which the characters are to be printed; each block of control data has an immediately preceding control block identifier. The bidirectional printer includes means for receiving the stream of sequential data, means for scanning the stream of data and means for inserting a control block identifier at the end of each control block which identifier corresponds to the identifier preceding the control block, whereby the stream of sequential data is made readable in both the forward and reverse directions within the printer.

Abstract: METHOD OF JUSTIFICATION FOR A LINE OF TEXT CONTAINING COMPLEX CHARACTERS of the disclosure A word or text processing system is provided having a bidirectional printer with formatting capability. A line of text is printed in one direction, and the printer is backspaced to form complex characters by adding overstrikes, such as underlining or accent marks. The formatting unit includes a storage mechanism for storing encoded space images, including variable width spaces, in a first scan pass. Space images overlapped by a backspace are deleted from the storage mechanism during the scan pass, and the number of spaces backspaced over is subtracted from the total count of expandable spaces available for justification. Upon detecting a space in the input data during the format pass, the system examines the space storage mechanism to determine if the image of the space is encoded therein. A space is expanded for line justification only if the space is encoded in the space storage mechanism. AT9-81-029
