I also have a Print Gocco. It is fun to use, but as someone else said,
supplies are hard to find and they are fairly expensive--the flash bulbs,
"film", and inks. If I remember correctly, one "film" (can't think of the
proper word) costs about 2.00--this can get VERY costly if you are planning
to have each student make a negative.
The printer does work well on both paper and fabric and the printing process
