     lptest -- generate	lineprinter ripple pattern

     lptest [length] [count]

     The lptest	utility	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 originally created to test printers,
     it	is quite useful	for testing terminals, driving terminal	ports for de-
     bugging 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.  Note that if count is to
     be	specified, length must be also be specified.

     A lptest utility appeared in 4.3BSD.
