Fpr copies its input onto its output, replacing the carriage

effects when printed using
lpr (1). The first character of each line determines the vertical spacing as follows:

A blank line is treated as if its first character is a blank. A blank that appears as a carriage control character is deleted. A zero is changed to a newline. A one is changed to a form feed. The effects of a "+" are simulated using backspaces.
