from the Poll Character xx MS on the front panel from 0 through 30).
This n milliseconds is called the poll delay. The poll character will be
removed from the input data stream and will not be processed. This
may cause problems with the transmission of binary data (e.g. control
codes, bit image, etc.). If a poll delay is started due to the receipt of a
poll character and another poll character is received, the second poll
character has no effect, and is removed from the input data stream. If a
transition (from buffer full to empty or online to offline) occurs during a
poll delay, the new printer state will be sent at the end of the poll delay.
The response characters are described in the following table:
Online and Buffer Empty
Online and Buffer Full
Offline and Buffer Empty
Offline and Buffer Full
SERIES 1 2 CHAR: – This protocol behaves exactly the same as the
Series1 Char except there is a two–character response to the host. The
response characters are described in the following table:
Online and Buffer Empty
Online and Buffer Full
Offline and Buffer Empty
Offline and Buffer Full
Baud Rate
This parameter sets the baud rate of the serial interface in the printer. Baud rate
is the speed at which serial data is transferred between the host computer and
the printer. The choices for the RS–232 and RS–422 interfaces are 600, 1200,
2400, 4800, 9600, 19200, 38400, 57600, and 115K Baud.
NOTE: If you select a baud rate that is greater than 19200, you may need
to use RS–422 to prevent data loss. You may need to increase the
Buffer Size in K parameter from the default (1 Kbyte), to improve
performance.
