lpf - lpd filter for nroff output
lpf -w width -l length
lpf is a filter which reads the output of nroff and converts lines with ^H’s to overwritten lines. Thus this works like ul(1) but is much better: it can handle more than 2 overwrites and it is written with some style.
This program was designed long ago, and is not much if any use today.
lpf will send itself the STOP signal when it encounters the character sequence ‘\031\1’.
