Holley developed and produced a series of drum printers. In June 1964, CDC bought out Holley and partnered with NCR and ICL to form CPI in Rochester.n 1982, CDC acquired a controlling interest in Centronics in exchange for CPI and $25 million in cash. CPI was merged into Centronics and eventually the Rochester facility was closed.
