       lptest - generate lineprinter ripple pattern

       lptest [ length [ count ] ]

       Lptest writes the traditional "ripple test" pattern on standard output.	In 96 lines, this
       pattern will print all 96 printable ASCII characters 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

       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.
