I stumbled upon this post from David Allen's blog, and I find the suggestion to print a label and copy-paste its title (plus maybe a description of the file's contents) into some digital (e.g. Excel) file that's searchable by a desktop search app a great idea.

The problem is, Brother's desktop software seems to be Windows-only :(

Any suggestions to get the same result with a Mac?

The only Mac-compatible labelers I've seen are Dymo's LW 330 and 400, and those seem to print on address labels only. I'd like to have one that prints on 1/2 in (12 mm) and/or 3/8 in (9 mm) label tape. It would be another nice touch if it wouldn't waste tape like crazy.

Can someone help me with that?
