But in reading and re-reading the docs. And in re-reading them yet again before responding to your suggestion just now, I can find no way to use that module to send a raw string as-is directly to the printer. After my eyes got "scrolled-out" I finally tried a text search for 'raw' and 'direct' in the pod. But no good.
I'd love for you to point out the option for that module I have missed that allows such a thing.
