摘要： A computer system operating under software control to provide output to a printer for printing. The computer system sets printer parameters to accommodate different forms of output to the printer. A word processing program stored in the computer memory is executed to couple information for printing to the printer with the printer in a first set of printer states. A typewriter emulator program stored in the computer memory is executable to couple information for printing to the printer and to set the printer states. The word processing program is interrupted by a hot key depressed by an operator, and the typewriter emulator program is entered, with the printer states being set in dependence upon printer state information for the typewriter emulator. When the typewriter emulator is interrupted by a hot key, the then-current printer states are stored and a set of default printer states for the word processor are restored prior to returning to execution of the word processing software.

摘要： A correction buffer for a typing system in which the correction buffer has a group of records, each record corresponding to an incremental distance on the medium which is printed upon. The records in the correction buffer contain information concerning characters entered through a keyboard by a typist including designations of entered characters and character attributes.

摘要： A method and apparatus for printing characters in bold form in a typing system. As disclosed, characters entered through an input device such as a keyboard are printed on paper, placed in a display and stored in memory substantially as they are entered. After a group of characters, such as a line of characters, have been entered and printed, those characters which are to be printed in bold form are identified from the information stored in the memory. The thus-identified characters are then printed a second time at a position slightly offset from that of the first printing of each of the characters.
