Fpr copies its input onto its output, replacing the carriage control characters with characters that will produce the intended effects when printed using lpr(1). The first character of each line determines the vertical spacing as follows:
- Blank One line
- 0 Two lines
- 1 To first line of next page
- + advance
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.
