A print component includes an address line, data lines, a fire pulse line, and a plurality of primitives, each primitive corresponding to a different data line and including a plurality of activation devices each corresponding to a different address of a set of addresses. A buffer receives data packets each including address data representative of an address of the set of addresses and print data for each primitive, places the print data on the respective data line of the corresponding primitive, and directs the address data to address logic which encodes the address data onto the address line in the order of reception of the address data by the buffer via the data packets. For each primitive, the activation device corresponding to the address on the address line activates a corresponding primitive function based on the corresponding print data when a fire pulse is present on the fire pulse line.
