For information about communicating with the host computer using the USB port, see the sample code located on the LabelWriter SE450 CD that came with the printer.
RS-232 Settings
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
