I actually do by paper made for PP. It goes through the copier But I only use the normal or best setting on the printer never fast 'cause sometimes it prints too fast and distorts the pattern you are copying. I also find that when I have used regular copy paper the thickness causes the thread to loosen when it is torn from the fabric. If you like to hand copy your patterns which is very time consumming, tracing paper would be fine, just not as acurate or fast as using PP paper.
