Until someone who knows the answer posts, I'll give you a gut feeling. It appears that the program is interpreting that set of keystrokes one way for the screen, and thinking it is a left-justify command when sending it to the engraver.

Slim chance it may be a communications problem from the computer to the engraver. Power off, remove the cables between the computer and engraver and reattach them twice. That will clean all those contacts and has a faint chance of being successful.
