I do enjoy a good puzzle.
My printer name does not contain spaces. I’ve re-downloaded the updated zip from github a few minutes ago and put it on my laptop at home (OSX 10.8.2), in case there was something weird about my work computer/printer setup, but the same “No such file or directory” error also occurs on my laptop.
I’m not sure what this means: “The printer settings may need to be adjusted to accept TEXT input.” I don’t see any options like that in my printer settings.
I am able to successfully print the file stuff.txt by typing “lp stuff.txt” in Terminal.
