lptest(8)
NAME
  lptest - Generates the line printer ripple test pattern

SYNOPSIS
  lptest [length [count]]

FLAGS
  length    Specifies the output line length when the 79-character default
	    line length is inappropriate.

  count	    Specifies the number of output lines to be generated when the
	    default 200-line length is inappropriate.  When count is
	    specified, length must also be specified.

DESCRIPTION
  The lptest command writes a traditional ripple test pattern to the standard
  output. In 96 lines, a pattern containing all 96 printable ASCII characters
  in each column position of the line is printed. In the pattern, each
  printed character is displaced rightward one character-column on each
  successive line. Originally created to test printers, the ripple test
  pattern is also useful for testing terminals, driving terminal ports during
  debugging, and for any other diagnostic task where a quick output of
  randomized data is needed.

FILES
  /usr/sbin/lptest
	    Specifies the command path.
