Cool, thanks for that suggestion. I was wondering if something like that would be necessary. I might try Keyboard2Serial, a shareware extension I found, that may save me having to try to figure out some of the communication myself. Beyond that, has anyone interacted with an Imagewriter directly in its ASCII mode? Any resources to point me to? Do I need to start reading up on how to configure it to be a terminal output or anything? I'll probably come back with more specific questions at some point, but I'd love a good starting point :beige:
