NAME
lptest - generate lineprinter ripple pattern
SYNOPSIS
lptest [ length [ count ] ]
DESCRIPTION
lptest writes the traditional "ripple test" pattern on stan-
dard output. In 96 lines, this pattern will print all 96
printable ASCII characters in each position. While origi-
nally created to test printers, it is quite useful for test-
ing terminals, driving terminal ports for debugging pur-
poses, 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.
