TOF Act at Prime Signal

is enabled.

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.
Trickle Time
This functionality prevents an attached host from timing out. 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.
