HOST INTERFACE Menu
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 “IEEE 1284 Parallel Interface” on page 255
for more details about the available modes (Compatibility, Nibble, and Byte).
Prime Signal
•
Enable (factory default). The parallel port will perform a warm start
(reboot) if the host asserts the prime signal.
•
Disable . The parallel port will not perform a warm start (reboot) if the host
asserts the prime signal.
TOF Action
•
Reset (factory 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 and 16 Kbytes, in 1-Kbyte
increments. The default is 16K.
NOTE: H-Series and OpenPrint HD products have a range of 1 to 256 and a
default of 64K.
