Abstract

In one example implementation, a replaceable printing component includes a fluid supply chamber, and a printhead on the fluid supply chamber. The printhead includes a memory storing a factory identification code that comprises a combination of digitized analog performance parameters. The printhead also includes electronic test components from which the analog performance parameters have been measured.
