In a printing head, which is employable in a printer, having a predetermined number of printing pins respectively connected to solenoids circularly disposed along a predetermined circle, the solenoids being arranged to be connected to another predetermined number of transistor arrays respectively including third predetermined number of transistor; the improvement in that two solenoids adjacently located with each other along the predetermined circle are respectively connected to separate transistor arrays. Thus, the current flowed through the solenoids can be prevented from undesirably increasing.
