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.

    How to open an LPT file

If you cannot open your LPT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LPT file directly in the browser:.
