No, I can't say as that I have noticed this. What I would do is scan the label of choice and clean it up in Illustrator, vectorize the lines, do fills, fix contrast and color. This sort of thing usually doesn't take long to do. For printing I am sure there must be templates out there for floppy labels which can be done on a Laserjet or such.

Also, my experience is to watch out for recent floppy media, like later than 1995 - and definitely after 2000. It seems that back when disks were a primary storage medium that they were more robust. Recent ones seem to corrupt more often, or even just break.
