DESCRIPTION
The lptest command 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 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. If count is to be specified, length
must also be specified.
