Chapter 4 HOST INTERFACE
IEEE 1284 Parallel (Bidirectional) Submenu
The IEEE 1284 interface is faster and more versatile than Centronics and
supports bidirectional communication. Configuration of this interface is
controlled from the host. Refer to
ΙΕΕΕ 1284 Παραλλελ Ιντερφαχε
ον παγε 117
more details about the available modes (Compatibility, Nibble,
and Byte).
Prime Signal
• Disable (default). The parallel port will not perform a warm start (reboot) if
the host asserts the prime signal.
• Enable . The parallel port will perform a warm start (reboot) if the host
asserts the prime signal.
TOF Action
• Reset (default). A form feed is performed before a warm start when the
prime signal is asserted from the host. This setting is used only if the
prime signal parameter is enabled.
• Do Nothing . Nothing occurs before a warm start when the prime signal is
asserted from the host.
Buffer Size in K
This option configures the amount of memory allocated for the IEEE 1284
parallel port buffer. You can specify between 1, 2, 4, 8, 16, 32, 64, 128, and
256 Kbytes. The default is 64 K.
Auto Trickle
Auto Trickle is used to prevent a host computer from timing out because the
parallel interface was busy for too long. When Auto Trickle is enabled and the
printer's buffers are almost full, the printer will begin to trickle data in (at the
rate set in the Trickle Time menu) until the buffers start to empty out.
