HOST INTERFACE
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.
Offline Process
Disable (the default). When set to disable, the printer does not process 
parallel/network data while offline.
Enable. When set to enable, the printer continues to process (but not 
print) the current network/parallel job while the printer is offline until the 
printer's buffer is full.
