Trickle Time

When the printer is printing data from a host and a second job is received by
the printer from a different host, Trickle Time prevents the second host from
timing out while it is waiting for its data to be printed. In order to support this
feature, the port has to be able to accept data from the host and store it for
future use.

For example, if the printer is printing a job from the serial port, and then
receives a second print job from the parallel port, the data from the parallel
port will “trickle” bit by bit into the printer buffer to prevent a timeout error from
being sent back to the host connected to the parallel port.

The selected value is the time that the printer waits before getting the next
byte of data from the host. The Trickle Time value should be less than the
host time out value, but not too much shorter or else the printer fills up its
buffer too fast. This function is not applicable for C/T hotport.
