I use a Brother label maker that does not attach to a PC, just a hand
held device. It only cost $30 and uses the TZ labels that are for
indoor/outdoor use. I use the black print on clear labels on zinc
markers. My labels are over two years old and still look like the day
they were printed.
I like the fact that the label maker is
portable. I keep it with my
plant supplies in the garage and can print
out a label as soon as I get
the plant and am ready to plant
This label maker prints on tapes from 1/4 to 3/8" wide and also
underline, italics, outline, etc and can print on 1, 2 or 3 lines.
don't need anything fancier than that.
