Note

•Buffer full recovery timing (DIP switch 3-2 and 3-3) and DTR flag set/X-off transmit timing (DIP switch

3-6) selections are enabled only when buffer operation is enabled (DIP switch 3-1 is OFF). If SW3-1 is ON, buffer full recovery timing is set to 32 bytes and DTR flag set/X-off transmit timing is set to 16 bytes.

•DSR/DCD signals (DIP switch 3-5) are enabled when RS-232D is selected.

Buffer full recovery timing

When the available space for bytes in the print buffer drops to 512 or 16 bytes, data entry is disabled. As the printer prints the data in the buffer, the vacant area for bytes increases. When this vacant area reaches one of the four values listed in the table below, data communication is resumed. These settings are selectable by using the DIP switches.
