printing via ataman

I am using my windows machine and emulating an ansi
terminal to open up the local printer port and write
escape sequence to enable printing. Our code returns a
status of 00, indicating that the port was found and
opened. Yet, our escape sequence is not being written
correctly to the port.
We are using ataman (altername terminal manager). When
not using Ataman, things work fine.
Is there anyone who is familiar with this issue that would
be able to help.
Any help would be greatly appreciated.
