NAME
       lptest - generate lineprinter ripple pattern

SYNOPSIS
       lptest [ length [ count ] ]

DESCRIPTION
       Lptest  writes the traditional "ripple test" pattern on standard output.  In 96 lines, this pattern will print all 96 printable ASCII char-
       acters in each position.  While originally created to test printers, it is quite useful for testing terminals, driving terminal	ports  for
       debugging purposes, or any other task where a quick supply of random data is needed.

       The length argument specifies the output line length if the the default length of 79 is inappropriate.

       The  count  argument specifies the number of output lines to be generated if the default count of 200 is inappropriate.	Note that if count
       is to be specified, length must be also be specified.
