NAME

  lptest - Generates the line printer ripple test pattern


SYNOPSIS

  lptest [length [count]]


OPTIONS

  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.
