[GreenKeys] Printer won't align model 15

Is there an audio cable from the Arduino, to the board (I’m assuming there’s a board in the loop)?  I had that problem early on and trying to remember — either the audio cable / port / jack was bad, the soldering points on the board were bad or it was the browser on my Pi that could not cache the stream fast/long enough (multiple problems always oh my!).

It prints perfectly fine when it is printing to itself. I currently have it hooked to an Arduino which is sending out RYRYRY in Baudot. To eliminate the question of is it the code, it is currently has a 22 second start delay, 22 second delay per bit, and a 31 second ending delay. That is currently being run through a solid state relay capable of switching at that speed. I know it can do this since it works with the keyboard when moving locally. Furthermore, the letters it prints are always the same depending on the speed setting, (although wrong) so it's not like there's a mechanical issue.
