That download link points to BCBDev, which no longer exists.

You said that the printer expects no Parity checking, but you are assigning
Even Parity instead.  You will have to call its SetCommDCBProperties()
method to set up the parity checking manually.

Also, you did not set any Handshaking options at all.  TCommPort does not
natively support setting up the handshaking, so you will have to call its
SetCommDCBProperties() method to set up the handshaking manually.

You did not inform the serial port that data was available for sending.  I
do not think TCommPort suppors this at all.

Also, WriteString() just dumps the string to the serial port and does not
wait to see if the string is actually transmitted.  You can use
WriteStringSlow() to ensure each character is actually transmitted.
