Property Name Description
Baud Rate The rate of signals transmitted per second. The larger the
number, the faster the data transmission.
Data Length The length of the data transmitted. It can be set to 7 or 8
bits.
Parity It can be set to Odd, Even or None. A parity bit is added to a
string of data bits to check if the data is correct.
Odd
The total number of “ones” in the data plus the parity
bit is an odd number.
Even
The total number of “ones” in the data plus parity bit
is an even number.
None
No parity check is used.
Stop Bit The stop bit is at the end of a string of data bits. It is used in
asynchronous transmission to let the receiver know that the
string of data bits being transmitted is end.
Flow Control
Flow control is used to control the data flow between the
computer and your printer.
XON/XOFF (DC1/DC3) It is software flow control that uses
