The invention provides for a printhead assembly that has a number of modular PCBs and a number of printhead integrated circuits (ICs). Each of the printhead IC's is respectively connected to one of the modular PCBs for operative control. Modular supports in the assembly define a raised portion and a recessed portion at an end thereof. Each PCB has electrical connecting strips which operatively overlie the respective recessed portions. At least one connecting member operatively connects respective PCBs to each other. Each connecting member has a series of parallel spaced conducting strips. The member is shaped and configured for fitment into a cavity defined by the raised and recessed portions of two abutting supports to connect the connecting strips of two PCBs via the conducting strips. The assembly also has a printer controller configured to synchronize operation of the respective PCBs during printing.
