Dave,
The toner used in laser printers is a form of plastic, if you get a paper jam in your printer and have to remove the paper before it has passed through the fuser assembly you will find the image rubs off the paper, the fuser assembly "fuses" i.e. melts, the image on to the paper, for "toner transfer" methods we then re-melt the toner, that is why it gets transferred from the paper to the PCB, i.e. the heat melts the toner and bonds it to the PCB, the melted toner likes the copper clad better than the glossy paper, the ink in magazines is a chemical composition and does not melt and will not transfer.
After transferring the image to the PCB its also a good idea to "seal" the image with TRF foil available from PCB "Fab in a box" or a cheaper alternative is toner transfer foil from craft shops, both do the same job, the reason for this is toner is quite porous and etchant will get into the minute spaces and possibly damage the tracks. [I've also read somewhere that putting the PCB under a bowl with a teaspoon of acetone next to it for 30 seconds to 1 minute does a similar job of "closing up" the toner particles, not tried this myself though!]
Try a test on some scrap PCB you will see what I mean.
