HOST INTERFACE
Resp. Polarity
The Resp. Polarity parameter must be set to match the response polarity of
your host computer.
•
Standard (default). Does not invert the response signal.
•
Inverted . Inverts the response signal sent to the host computer.
Busy On Strobe
•
Enable (default). Asserts a busy signal after each character is received.
•
Disable . Asserts a busy signal only when the print buffers are full.
Latch Data On
Specifies whether the data is read on the leading or trailing edge of the data
strobe signal. The default is leading.
Prime Signal
•
Enable (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 (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
Configures the amount of memory allocated for the Centronics parallel port
buffer. You can specify between 1 and 16 Kbytes, in 1-Kbyte increments.
The default is 16K.
NOTE: H-Series products have a range of 1 to 256 and a default of 64K.
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.
