Super Labeler v3.0 by Greg Martens (1986) - Don't let the intro screen fool you, I'm sure the name used there is only because the longer name wouldn't fit on the floppy disk image.  Anyway, Super Labeler is a pretty simple program but gets the job done.  Although designed with the Panasonic KX-P1091 in mind, it works find with Epson and compatible printers including the Commodore MPS-803 which I used for testing.
