Will remanufactured toner void my printer warranty?

If a printer vendor tells you that your warranty is or will be voided by using remanufactured cartridges, refer them to the Magnuson-Moss Warranty Improvement Act, 15 U.S.C. § 2302.

“No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer’s using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name; except that the prohibition of this subsection may be waived by the commission if: The warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and the Commission finds that such a waiver is in the public interest.”
