Abstract

An operator-initiated clearing of a printer's buffer is a desired feature for those who have occasion to truncate a document's printing before the end of file has been reached. Clearing the buffer allows the next file to be printed without undue delay or wasted printer ribbon/ink/paper and with reduced operator frustration.

Printer Buffer Flush Function

      An operator-initiated clearing of a printer's buffer is a
desired feature for those who have occasion to truncate a document's
printing before the end of file has been reached. Clearing the buffer
allows the next file to be printed without undue delay or wasted
printer ribbon/ink/paper and with reduced operator frustration.

      The Printer Buffer Flush Function may be implemented in a
printer or external printer buffer unit.

      This function can be implemented to occur when:
           1)   A proper escape sequence is received from an attached
computer.
           2)   An operator (user) presses a button or sequence on
the printer or buffer unit's control panel.
           3)   A logic-specified period of time has elapsed since
data to be printed has been received and the printer is in an on-line
or other ready state.

      Upon the receipt of a clear buffer command by one of these
methods a status reset should then be made to occur in the
printer/buffer logic to:
           1)   indicate buffer empty and discard/ignore any buffer
content
                or
           2)   to force any contents held in the buffer to be
printed and then buffer empty to be set as a true state.
