NAME
       lptest - Generates the line printer ripple test pattern

SYNOPSIS
       lptest [length [count]]

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