To transfer toner you need two things to happen.
First the toner has to stick to the transfer sheet well enough to allow the process to happen. Alu foil and parchment paper are too slick. The toner falls off to easy.
The second is that after the toner is fused to the PCB the transfer sheet has to release the toner. The problem with normal paper is that the toner is absorbed by the paper. To prevent this use a paper with a high clay content. Slick colored magazine pages often contain clay to make the paper smooth.
