lp is the standard command to submit print jobs to printers managed by CUPS (Common Unix Printing System). It queues files for printing and provides options to control print quality, number of copies, page selection, and other print job attributes.

Requires CUPS to be installed and running. Printer must be configured. Some options depend on printer capabilities. Network printers may have delays.

-o sides=two-sided-long-edge - Duplex printing
-o media=A4 - Paper size
-o landscape - Landscape orientation
-o fit-to-page - Scale to fit page
