+DESCRIPTION
+       lp submits files for printing or alters a pending job.  Use a filename of "-" to force printing from the standard input.
+
+   THE DEFAULT DESTINATION
+       CUPS  provides many ways to set the default destination. The LPDEST and PRINTER environment variables are consulted first.  If neither are set, the
+       current default set using the lpoptions(1) command is used, followed by the default set using the lpadmin(8) command.
+
+OPTIONS
+       The following options are recognized by lp:
+
+       --   Marks the end of options; use this to print a file whose name begins with a dash (-).
+
+       -E   Forces encryption when connecting to the server.
+
+       -U username
+            Specifies the username to use when connecting to the server.
+
+       -c   This option is provided for backwards-compatibility only. On systems that support it, this option forces the print file to be  copied  to  the
+            spool directory before printing.  In CUPS, print files are always sent to the scheduler via IPP which has the same effect.
+
+       -d destination
+            Prints files to the named printer.
+
+       -h hostname[:port]
+            Chooses an alternate server.
+
+       -i job-id
+            Specifies an existing job to modify.
+
+       -m   Sends an email when the job is completed.
+
+       -n copies
+            Sets the number of copies to print.
+
+       -o "name=value [ ... name=value ]"
+            Sets one or more job options.
+
+       -q priority
+            Sets the job priority from 1 (lowest) to 100 (highest).  The default priority is 50.
+
+       -s   Do not report the resulting job IDs (silent mode.)
+
+       -t "name"
+            Sets the job name.
+
+       -H hh:mm
+
+       -H hold
+
+       -H immediate
+
+       -H restart
+
+       -H resume
+            Specifies  when  the  job  should be printed.  A value of immediate will print the file immediately, a value of hold will hold the job indefi‐
+            nitely, and a UTC time value (HH:MM) will hold the job until the specified UTC (not local) time.  Use a value of resume with the -i option  to
+            resume a held job.  Use a value of restart with the -i option to restart a completed job.
+
+       -P page-list
+            Specifies  which  pages  to  print  in  the  document.   The  list  can  contain a list of numbers and ranges (#-#) separated by commas, e.g.,
+            "1,3-5,16".  The page numbers refer to the output pages and not the document's original pages - options like "number-up" can affect  the  num‐
+            bering of the pages.
+
+   COMMON JOB OPTIONS
+       Aside from the printer-specific options reported by the lpoptions(1) command, the following generic options are available:
+
+       -o media=size
+            Sets the page size to size. Most printers support at least the size names "a4", "letter", and "legal".
+
+       -o orientation-requested=4
+            Prints the job in landscape (rotated 90 degrees).
+
+       -o sides=one-sided
+            Prints on one side of the paper.
+
+       -o sides=two-sided-long-edge
+            Prints on both sides of the paper for portrait output.
+
+       -o sides=two-sided-short-edge
+            Prints on both sides of the paper for landscape output.
+
+       -o fit-to-page
+            Scales the print file to fit on the page.
+
+       -o number-up={2|4|6|9|16}
+            Prints 2, 4, 6, 9, or 16 document (input) pages on each output page.
+
+CONFORMING TO
+       Unlike  the  System  V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", or "#".  Also, printer
+       and class names are not case-sensitive.
+
+       The -q option accepts a different range of values than the Solaris lp command, matching the IPP job priority values (1-100, 100 is  highest  prior‐
+       ity) instead of the Solaris values (0-39, 0 is highest priority).
+
+EXAMPLES
+       Print two copies of a document to the default printer:
+
+           lp -n 2 filename
+
+       Print a double-sided legal document to a printer called "foo":
+
+           lp -d foo -o media=legal -o sides=two-sided-long-edge filename
+
+       Print a presentation document 2-up to a printer called "foo":
+
+           lp -d foo -o number-up=2 filename
