Cable 6 Foot Null Modem DB9F to DB25M

This is a 6 foot null modem or serial printer cable that is required to connect a serial printer (receipt or regular printer) to a computer or other device such as a electronic cash register. One end of cable is 9 pin female (this end usually connects to computer/device) and the other end is 25 pin male for connecting to the printer. A standard, non-null serial (modem) cable will NOT work with serial printers.
