Installing Options 4-5
If you will connect your printer to any type of serial interface,

several types of interface cables. However, you can use any
interface cable that meets the printer specifications listed below.
(See your computer manual for any special computer

Also be sure to read “Using a Serial Interface” on page 4-12 for
