Parallel I/F bi-directional mode
The Parallel Interface bidirectional transfer mode is used when
this feature is on. If bidirectional transfer mode is unnecessary,
turn this off.
Packet mode
Make sure to select Auto when you print from Windows
applications using the printer driver included on the printer
software CD-ROM that comes with the printer. Turn this feature
off if you have connection troubles while printing from
applications based on other operating systems such as DOS.
Serial baud rate
This setting is available only when data is transferred via a serial
interface. Use this option to set the data transfer rate (baud) for
the serial interface. The baud rate is measured in bits per second
(bps). See your computer manual and software documentation
for the proper setting.
Serial parity
This setting is available only when data is transferred via a serial
interface. The parity bit is added to data and detects errors on
the data. When this option is set to None, the parity bit is not
added to data. When this option is set to Ignore, the parity is
added to data, but the printer receives the data even if an error is
detected.
Serial data length
This setting is available only when data is transferred via a serial
interface. Set the data length of the serial interface to 8-bit or
7-bit. See your computer manual and software documentation
for the proper setting.
