Short for Line Printer Terminal, LPT is used by IBM compatible computers as an identification for the parallel port such as LPT1, LPT2, or LPT3. This is commonly required when installing a printer on an IBM compatible computer. The majority of all computers utilize LPT1 and do not have an option for another LPT port unless additional ports are added to the computer.
