                     31: .Nm Lptest
                     32: writes the traditional "ripple test" pattern on standard output.
                     33: In 96 lines,
                     34: this pattern will print all 96 printable ASCII characters
                     35: in each position.
                     36: While originally created to test printers, it is quite
                     37: useful for testing terminals,
                     38: driving terminal ports for debugging purposes,
                     39: or any other task where a quick supply of random data is needed.

                     42: .Ar length
                     43: argument specifies the output line length if the the default
                     44: length of 79 is inappropriate.

                     47: .Ar count
                     48: argument specifies the number of output lines to be generated if
                     49: the default count of 200 is inappropriate.
                     50: Note that if
                     51: .Ar count
                     52: is to be specified,
                     53: .Ar length
                     54: must be also be specified.
