You have a much better chance of tripping over the cord, having the printer fall on you and hurt you that way than it giving you cancer.
If you are not worried about it hurting you that way, don't worry at all about the cancer risk.
The main part is, don't move to California, seems if you do, all sorts of things that are fine elsewhere will harm you in that state
Also, don't drink the printer ink or smear it all over your body and sleep in it every day. You pretty much need to do that for it to do any damage to your body.
