LPT

Abbreviation for Line Print Terminal. On a personal computer this is the usual designation for a parallel port connection to a printer or other device such as a scanner or camera. LPT connections are numbered LPT1, LPT2, LPT3, etc.; most computers have at least one. More parallel ports can be added by installing parallel port adapter cards. Parallel computer connections traditionally have used the Centronics parallel interface for printer communication. A newer standard called EPP/ECP supports the older interface while providing faster communication for a range of devices, including scanners and video cameras.
