In order for the host computer to communicate with the LabelWriter SE450 printer, the communication parameters must be set as follows:
|
Baud Rate |
9600 |
|
Data Bits |
8 |
|
Stop Bits |
1 |
|
Parity |
None |
These settings can often be set using a BIOS setup program or an Operating System Control Panel application. For embedded applications, you may need to build these settings into the embedded system's initialization code.
Most languages provide a command or function to initialize a serial port.
If programming under Windows using Microsoft C/C++, use the function:
| bios_serialcom() |
Other C compilers offer a similar function. Consult your compiler user guide for the appropriate function to use to configure a serial port.
If you are using the Unix OS, you’ll need to configure the RS-232 port as a dumb printer port, with no special handling, control characters or form feeds. The LabelWriter printer will handle these functions internally.
