There are some fabrics that work with laser printers and others that work with ink jet printers. For some, you print directly on the fabric, others are ink transfers.
There are differences in the brands of fabric, too. I bought one that said "full directions inside" and the directions inside said the the fabric couldn't be washed -- what is the point of printing on fabric which can't be washed? This unwashable fabric was something like "Jacquard" brand. There was a review of fabrics for printing about 5 years ago. I think June Tailor was one brand that performed well. I haven't had enough experience with washing fabrics after printing on them to recommend a brand. So, at least be sure it gives the directions on the outside of the package, or ask to see the inside of the package before buying.
