In May 2018 King and fellow Maine senator Susan Collins introduced the PRINT Act, a bill that would halt collections of countervailing duties and anti-dumping duties on Canadian newsprint and require the U.S. Department of Commerce to conduct a study of economic health of printing and publishing industries. Proponents of the bill argued it would offer a lifeline to the publishing industry amid newsprint price increases. Critics accused it of setting "a dangerous precedent for future investigations into allegations of unfair trade practices."
