The paper rolls are guaranteed to work efficiently with your machine printhead to provide crisp, clear, black images. The reliability and performance of a thermal printer is directly related to the quality of the supplies, including the paper, used by the customer. The IBM® Testing Process is an "Industry Standard" test for the thermal papers used in the marketplace. To be IBM® approved, the paper must pass a 100km of paper printhead test without abrasion or build-up, with no cutting failures. IBM testing only confirms that the use of approved papers will not negatively affect the operating life of an IBM thermal printer. Manufactured to OEM specifications.
