Abstract
A print head for use with a printer. The print head includes an input that receives data or commands associated with printing from the printer. A memory component of the print head is connected in communication with the input and is configured to bi-directionally communicate information to the printer via the input. For example, the memory component may be soldered to a circuit of a print head and connected to a data line normally used to communicate print data to the print head. In this manner, the print head may hold configuration information in the memory module for easy upgrades without an additional dedicated communication line. Also, printers may be upgraded, and print heads retrofit, with the memory component without installation of a dedicated input or communication line.
