Ive been told that the HP 1020 laser printer has a black toner ink with a high content of iron oxides. Im going to buy one for that very reason but before I do so, Im wanting to know if anyone knows differently? I need a laser printer that uses black toner with a high iron oxide content. Ultimately, I am going to print my own decals that will be used in a glass kiln and wont be subjected to burning away due to high temperatures. If anyone has any experience with this, please advise & thank you in advance!!
