the Wikipedia link you gave says: exposure of a person repeatedly touching thermal printer paper for 10 h/day, such as at a cash register, could reach 71 microg/day, which is 42 times less than the present tolerable daily intake (TDI).
Anyway I did say potential, but as the researcher suggests pregnant women working as cashiers should be careful and err on the side of caution.
You are being overly dramatic.
