We have a very fast line printer (LP27) under 4.1 and it is handy to use for nroff "draft" output. The problem is that the line printer filter (lpf.c) called by lpr strips out all underlining and also does not handle form feeds correctly (the form feeds come from another program, not nroff). If you cat the files directly to /dev/lp the underlining and form feeds work correctly, but the underlining is brute force by the driver (every time a backspace is encountered a carriage return is output and spaces are then output up to the correct column - very slow !!). However, on a multi-user system, cat'ing directly to /dev/lp should be frowned upon. The LP27 also slews much faster than it single spaces, so a nice filter to change all the blank lines output by pr, for example, to skip to the top of the next page, would be nice. Anyone hacked up lpf, before we tackle it ? Richard Stevens Health Systems International { ihnp4 | decvax | hao | seismo } ! kpno ! hsi ! stevens
