What is a PJL file?

PJL files mostly belong to HP LaserJet. Printer Job Language (PJL) files are plain text command files that control printer operations.
These files, developed mainly for HP LaserJet printers, contain instructions to control job management and printer configuration. The commands within a PJL file instruct the printer to perform actions such as:

Starting and ending print jobs

Setting printer configurations

Reporting error conditions and status

Because the content is plain text, you can open and view a PJL file with any text editor. However, editing these commands without proper knowledge can disrupt printer operation.
FilExt.com additional details: PJL files offer remote management features and enable detailed control over printer behavior. They work as a script that the printer firmware interprets to manage tasks behind the print process. For more information, visit the official site at HP.
