'''Computer Peripherals, Inc.''' ('''CPI''') was an American manufacturer of [computer printers](/source/Printer_(computing)), based in [Rochester, Michigan](/source/Rochester%2C_Michigan).

CPI's precursor, Holley Computer Products, was formed as a [joint venture](/source/joint_venture) between [Control Data Corporation](/source/Control_Data_Corporation) (CDC) and the [Holley Carburetor Company](/source/Holley_Performance_Products) in April 1962. Holley developed and produced a series of drum printers. In June 1964, CDC bought out Holley and partnered with [NCR](/source/NCR_Corporation) and [ICL](/source/International_Computers_Limited) to form CPI in Rochester.<ref>{{cite web |url=http://www.cbi.umn.edu/collections/cdc/acquisitions.html |title=CDC Acquisitions to 1984  |work=Charles Babbage Institute}}</ref> The facility was located near Rochester Road and Tienken Road, immediately north of North Hill Elementary School.

In the early 1970s CPI also had a branch in Valley Forge, Pennsylvania. This division made punched card readers and 9-track magnetic tape drives for both parent companies (CDC and NCR).

In 1978 CDC bought [controlling interest](/source/controlling_interest) of CPI. CPI produced several train printers under the CDC and Fastrain brands, including the CDC Model 512 (1967), the Fastrain A 1200 LPM (1969) and the Fastrain 9372-III 2000 LPM (1976).<ref>{{cite book |last=Webster |first=Edward |year=2001 |title=Print Unchained: 50 Years of Digital Printing, 1950-2000 and Beyond |publisher=Dra of Vermont |isbn=0-9702617-0-5}}</ref>

In 1977, CPI began manufacturing printers at a factory in Stevenage, Herts, UK that was originally used for the manufacture of ICL1900 computers. By 1979, the factory also made 9-track tape drives which were used in ICL and CDC computers, and were sold with industry-standard interfaces for use with other manufacturer's computers.

In 1982, CDC acquired a controlling interest in [Centronics](/source/Centronics) in exchange for CPI and $25 million in cash. CPI was merged into Centronics and eventually the Rochester facility was closed.
