Abstract

A typewriter when used as a printer of a personal computer has certain modes selected from the keyboard of the typewriter with a different key sequence for each mode. A typewriter may have the following modes, for example: 1. automatic line feed on carriage return (on or off), 2. page length default (select or not select), and 3. character set (select or not select). At the time of manufacture, each of these modes may be set in the software of the typewriter. For example, depression of a code key and the numeral 1 key can set the automatic line feed on carriage return to be on. The software also could include a final key sequence in which a summary of the settings would be printed.

Keyboard Entry of Printer Mode Settings

A typewriter when used as a printer of a personal computer has certain modes selected from the keyboard of the typewriter with a different key sequence for each mode. A typewriter may have the following modes, for example: 1. automatic line feed on carriage return (on or off), 2. page length default (select or not select), and

3. character set (select or not select). At the time of manufacture, each of these modes may be set in the software of the typewriter. For example, depression of a code key and the numeral 1 key can set the automatic line feed on carriage return to be on. The software also could include a final key sequence in which a summary of the settings would be printed. The typewriter has a constant memory through using a battery-backup random-access memory (RAM) so that all settings will remain until changed by the user. If the batteries were ever disconnected, the modes would return to their default. For example, this could be the automatic line feed on the carriage return being on, the page length default being selected, and the character set being selected. This arrangement enables the user to easily change various modes since previously-used switches have usually been in the back or beneath cover plates so as to not be readily accessible. This also saves the cost of the switches, associated board space, and cover holes.
