Unit 4: Printer Configuration
GL408-412e Operator Manual
4-43 PN: 9001163A
When the printer is printing data from a host and a second job is recieved by the printer from a
different host, Trickle Time prevents the second host from timing out while 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, 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 trckle bit by bit into the print buffer to
prevent a timeout error from being sent back to the host connected to the parallel port.
The selected value should be less than the host timeout value, but not too much shorter or else
the printer fills up its buffer too fast. This function is applicable for C/T hotport.
the options are 1/4, 1/2, 1, 2, 4, 8, and 16 seconds and Off. The factory default is 1/4.
This is the value used by the printer to time out from the current port and check the other selected
Port Types fro data print. When the printer has not received data from the host after a certain
period of time, it must timeout in order to service other ports.
The factory default is 10 seconds with an allowable range of 1 to 60 seconds.
When a fault condition occurs in the printer, normally only the active port reports the fault to the
host. Whe the Report Status menu option is enabled, the port will report any fault even when it is
not the current, active port.
The options are Disable and Enable. The factory default is Disable.
Data Terminal Ready. This configuration is part of hardware flow control and determines when the
Data Terminal Ready (DTR) signal is generated. This signal indicates if the printer is ready to
receive data.
• True - factory default. Continuaously asserts the DTR signal.
• False - never asserts the DTR signal.
• On-Line and BNF - buffer not full. Asserts the DTR signal when the printer is online and the
internal serial buffer is not full.
• Off-Line or BF - buffer full. Asserts the DTR signal when the printer is offline or the internal
serial buffer is full.
• On-Line - asserts the DTR signal when the printer is online.
This configuration is part of hardware flow control and determines when the Request to Send
(RTS) signal is generated. This signal indicates whether or not the printer is ready to receive
data.
• On-Line and BNF - factory default. Asserts the RTS signal when the printer is online and
the internal serial buffer is not full.
• Off-Line or BF - buffer full. Asserts the RTS signal when the printer is offline or the internal
serial buffer is full.
• On-Line - asserts the RTS signal when the printer is online.
• False - never asserts the RTS signal.
• True - factory default. Continuaously asserts the RTS signal.
This option is for the Series1 protocol. Whenever the printer receives this character, it sends a
response to the host indicating the current state of the printer (refer to Series1 protocol).
The allowable range is 00 to FF Hex, and the factory default is 00 Hex.
