The cable required to connect to a printer (or any other output device) is called a Null-modem cable (NMC). A technical explanation and drawing of the connections required is given in Appendix 1.

A Null-modem cable has Cable-sockets at each end to plug into the Chassis-plugs on the RS232C and the printer. If your printer has a Chassis-socket, then you will also require a converter cable comprising two back-to-back Cable-plugs.
