Print one or more files.
lpr [options] [files]
-Pprinter prints to the specified printer (the name appears in /etc/printcap).
-#N (where N is a number) prints that many copies of each file.
-h suppresses the burst page (the first page, with user information).
-m sends mail upon completion of a print job.
-r removes the file after printing.
-J jobname prints this job name on the burst page.
-U username prints this user name on the burst page.
The lpr command prints the specified files by using your system’s print-spooling system. If no filenames are specified, lpr reads input from the standard input. You can print to a specific printer with the -P option.
