Heat transfer must be accompanied by Epson printer, for the reason that after infiltrating inks into cartridge or ciss for epson, pattern on common printing paper just can be printed on chemical fabrics, difficult for cotton fabrics which should be printed by specialized heat transfer paper.
For the reason why heat transfer must be accompanied by Epson printer, the printing methods of Epson printer is piezoelectric printing, which change electricity in its nozzle to make different pressure to print different color pattern through computer control; other brand printer like Canon belongs to hot foaming principle which is printing inks on heat transfer paper by heating.
Piezoelectric printing will not change the chemical characteristic of sublimation inks because of just machinery pressure-changed. Therefore, it is very popular among heat transfer. If sublimation inks are printing by hot foaming printer, chemical components will be changed, which will result in colour cast and non-transferred paper.
