I had this problem when I bought a house and inherited an almost-new top of the line refrigerator that someone kept raw fish in. The smell when I opened the door knocked me over and NOTHING I tried got rid of it! So just when I was ready to throw out a $2,000 refridge, someone told me to buy a can of fresh coffee grounds and spread the whole can out on a cookie sheet and let it sit in the refridge for a couple of days. The fish smell was GONE!!!
I would take a large box, scatter fresh (unused) coffee grounds right out of the cofee container into the bottom of the box, set the printer in it and close the box top. Let it sit for a couple of days and I bet the smoke smell will be gone. Hope this helps.
