Yes, a single NUL was what I had in mind. It's better than what happens if you try to play the EDDAC _without_ checking whether it is plugged in! But since (I expect) all printers ignore the NUL except in the middle of an escape sequence, and since you are very unlikely to be doing this check in the middle of an escape sequence, I think it should be harmless. imc
