   (successfully or unsuccessfully).

      +---+------+----+
      | N | Name | LF |
      +---+------+----+
      Command code - 'N'
      Operand - File name

   This command specifies the name of the file from which the data file
   was constructed.  It is returned on a query and used in printing with
   the 'p' command when no title has been given.  It must be 131 or
   fewer octets.

7.8 P - User identification

      +---+------+----+
      | P | Name | LF |
      +---+------+----+
      Command code - 'P'
      Operand - User id

   This command specifies the user identification of the entity
   requesting the printing job.  This command must be included in the
   control file.  The user identification must be 31 or fewer octets.

7.9 S - Symbolic link data

      +---+--------+----+-------+----+
      | S | device | SP | inode | LF |
      +---+--------+----+-------+----+
      Command code - 'S'
      Operand 1 - Device number
      Operand 2 - Inode number

   This command is used to record symbolic link data on a Unix system so
   that changing a file's directory entry after a file is printed will
   not print the new file.  It is ignored if the data file is not
   symbolically linked.

   value for the width is 132.
