In my limitted experiences so far, I can't say the time between
printing and transferring is important.
However, I have found that touching the toner on the paper appears to
cause problems (I have oily skin). I also suspect that humidity might
have some effect on the transfer process, but have yet been able to
verify this.
I have found that the time from transfer to soaking in water is
important for a fast release. I am currently using a heavy gloss
paper. If I let the paper/pcb cool down after transfer, then soak it,
it takes a very long time for the paper to release from the PCB.
If, after transfer, I put everything in cool water right away, the
paper releases very quickly by comparison.
