A friend complained that she suddenly couldn’t print from Apple’s Pages.app. The print dialog would take forever and then she still couldn’t print anyway. After some discussion I suggested looking for a corrupt font. Sure enough, she replied:
I chucked out lots of fonts I don’t need, got Font Finagler, cleared the font caches, let the permissions repair run once again, and now Pages happily prints all kinds of stuff including the documents that didn’t, and in a jiffy.
