Looking for piezo printer with disposable heads

[Hanno Evard]

I'm doing experiments with printing some chemicals onto paper. Unfortunately the compound I print seems to react to the high heat of the thermal printer heads (I'm using a HP printer right now) and permanently clog the heads.

Can anyone suggest a printer with piezoelectric printing heads but which would have disposable heads? The goal would be that in case the heads still clog then I could simply replace the heads and I don't need to buy a new printer.
