I have actually used the tool, but only briefly because I enjoy the convenience and consistency of printing directly from Lightroom. (I had margin width issues when using Epson Print Layout). Back at the computer today I started up the program, and you are correct (my apologies), Advanced Black and White should be in the Colour Settings > Type menu (see attached image).
On the epson website you linked to (the same where I originally got the program) only the newest line of "SureColor" printers listed as being compatible, so while it might "work" with the 3880, this might just be an incompatibility issue.
Sorry for the mixup,
Mike
