I am struggling with finding a printer and toner that I can use to print onto water slide technology for kiln firing bisque ceramics. I know I will require toner with more than 30% iron oxide, also that the magnetic quality of the toner is more important that the oxide levels, that is as much as I know so far. I believe HP printers are the best for this and am also starting to believe you can't get the printers and toners anymore as they have gone out of fashion? Does anyone have any further good oil?
