As long as you follow the instructions and have the fabric securely pressed to the freezer paper there shouldn't be a problem with using any inkjet printer. <G>
My favorite printer to use is a cheap (I think we paid about $65 for it) HP printer. It is fairly small, nothing fancy and lightweight. I can carry it to do demos with and so forth.
There is lots of info in the first (free) chapter of the Inklingo Handbook.
And most printer companies do have info on printing on fabric. HP even sells fabric treated for permanent printing on fabric. But with Inklingo you don't want permanent. You don't want to treat the fabric, except so that it will stick to the freezer paper. Easy and fast.
And fun,
