I was thinking about this and knowing how the fuser is constructed in the laser jet the wax would only get on the Teflon sleeve . since it would provide additional lubrication I would see no issues from that. The other parts of the printer are not at high temperature so would not be an issue. If it did muck up the fuser the sleeve is replaceable if you do disassembly of the fuser or you likely could just clean it.

Wax paper works fine. I have been using it for months with no noticeable issues. I use Reynolds wax paper. Other off brand wax paper yieds poor results.
