I have a few of these presses - mine are set to 125 idle, 167 temp for 170 seconds with a light to medium pressure. I use one piece of tape that I thread through the handle, no need for any more as the blanket applies pressure, so ink doesn't migrate from top/bottom of paper.

I don't normally print top to bottom, but the ones I have done have came out fine - without preheating the mug.

Cheers John
