Parallel Interface Menu
Prime Signal
ENABLE (the default). When set and the host asserts the PRIME SIGNAL,
the parallel port will perform a warm start.
•
DISABLE. The parallel port will not perform a warm start when the host
asserts the PRIME SIGNAL.
TOF Action at Prime Signal
TOF (Top–of–Form) ACTION AT PRIME SIGNAL determines whether or not
a form feed is performed before a warm start when the prime signal is
asserted from the host. This setting is only used if PRIME SIGNAL parameter
is enabled.
•
FORM FEED AT RESET (the default)
•
NO FORM FEED AT RESET
Buffer Size in Kbytes
This parameter determines the size of the input buffer. The maximum input
buffer is up to 256K. 64K is the default.
Dataproducts Menu
Although this interface is supported, it is not currently offered on 6400-D
Series models.
IEEE 1284
The IEEE 1284 interface is faster and more versatile than Centronics and
supports bidirectional communication. The IEEE 1284 interface has no
parameters that are adjustable via the operator panel. For more information,
see Chapter 5, "Printer Interfaces."
Parallel Hotport
This option gives the printer the ability to handle multiple data streams
simultaneously. It allows the printer to service hosts attached to the parallel
ports as if they were the only interface connected.
Trickle Time
This functionality prevents an attached host from timing out. In order to
support this feature, the port has to be able to accept data from the host and
store it for future use. The selected value is the time that the printer waits
before getting the next byte of data from the host. Set the value to be less
than the host time out value. If the value is too much shorter, the printer fills
up its buffer too fast. Values are: 1/4 Sec (the default), 1/2 Sec, 1 Sec, 2 Sec,
4 Sec, 8 Sec, 16 Sec, and Off.
