What is an LPT file?

LPT files mostly belong to Printer Driver. An LPT file is a specialized file that stores printer output data.
It may serve several functions, such as:
  • Laser Printer Trace: A file that records details of a print job sent by a laser printer.
  • Label Printing Template: A document used to set up and drive label printers, as seen in systems from BradyWorkstation or Texas Logic List Processor (Texas Logic).
  • Report File: A file generated in a compound format for use with reporting tools like Crystal Reports (SAP) or even as a Microsoft Access project file with JetDB structure (Access).
    • This file is not intended for casual editing. Some LPT files are text-based, but many use binary or compound structures that require specific printer drivers or report viewing software to be properly read.
    FilExt.com tip: The term LPT is linked with historical printing functions (often referring to Line Print Terminal), which has evolved into storing detailed print job operations today.
