I think what is happening is the install script name is what is used to either create or look for directory with the quad files, and it needs to match the name of the printer installed.
Alternatively, you might just need to change the name of the printer in System Preferences from Quad3885 to Quad3880, and leave the names of the folder and install scripts alone.
Hope that helps.
