According to the vendor of Transfer magic all Inkjet inks and transparency films are not created equal. He recommend using an Epson Injet printer that uses the Epson T060120 black ink cartridge and Epson transparency film S041064. Most Epson printers use that black cartridge. Other printers/inks and inkjet transparency films may work but since I already had an Epson printer that uses the recommended cartridge I had no reason to test any others.
