ls /dev/cu*
In my instance the USB adapter was /dev/cu.usbmodem14101
Then run:
screen /dev/cu.usbmodem14101 115200
Where 115200 is the baud rate.
Et voila, you can see what the printer is doing.

Library not loaded: @executable_path/../Frameworks/asneu.framework/versions/a/asneuThis problem stems from the fact that the system drive is a case sensitive file system; in a similar vein, we were recently unable to install Adobe CC on a similar system as it is also incompatible with a case sensitive file system. We fixed our Lightroom issue by changing the path from:
/Applications/Adobe Photoshop Lightroom 5.app/Contents/Frameworks/asneu.framework/Versions/Ato:
/Applications/Adobe Photoshop Lightroom 5.app/Contents/Frameworks/asneu.framework/versions/aThe above assumes a normal install to the /Applications directory. If you are game to try the change yourself, you make the change via Terminal:
cd /Applications/Adobe\ Photoshop\ Lightroom\ 5.app/Contents/Frameworks/asneu.framework sudo mv Versions versions cd versions sudo mv A aNow try and start Lightroom and you should be successful.
