We are doing word processing using VI and NROFF on the Pyramid
here. We hooked an HP LaserJet II to the printer ports of our
terminals through a Logical Connection sharing box.
Question:
How does one get an escape sequence out of NROFF? I would
like to use bold face, italics, underline etc. that are available
from within the LaserJet. These require the construction of a
macro to transmit the appropriate character string starting with a
real escape ($1b). How do I get VI to put a literal value in the
file, alternately, some sequence that NROFF will translate into a
hex 1b? I can't find anything in the books I have.

In your case, you can try C-V ESC, you would get something looking like "^[" which is a standard representation of ESC in VI, and it does have a value of hex 1b.

Thanks, this works fine and helps a lot in creating the scripts that I use to spool to the LaserJet (do a reset, set noskipoverperf, set 66 lines and some set landscape). The NROFF problem remains however. I can't get an escape through NROFF. This thing uses several printer drivers, does anyone know where these printer drivers are stored? Mabye I can figure out how to modify one to configure the LaserJet. Oh, yes, the computer is eight miles away, not too practical to connect the printer directly. We don't all have the luxury of our own machines. The LaserJet is currently shared by two 5420/2's, one vt240, and two IBM AT's running dedicated applications. -- Jim Harvey | "Ask not for whom the bell Michigan Bell Telephone | tolls and you will only pay 29777 Telegraph | Station-to-Station rates."

You *can* put control characters in an nroff file. Example, think of the backspace. That's what nroff uses to underline. You need to watch out for your lpr command though. Mine runs the file through a filter specified by printcap. The filter then strips out all non-printing characters. To bypass the filter, I must specify lpr -l filename OS: Xenix 3.4 Machine: Intel 310 Hugh Dempsey

How about writing a small filter program that translates the underscores and backspaces in output from nroff to printer escape codes? I wrote various of them for matrix printers or daisywheels, and it even worked with eqn. lex(1) is quite convenient for this sort of work, and it certainly is fast enough for printers :-) Wietse Venema -- uucp: mcvax!eutrc3!wswietse | Eindhoven University of Technology bitnet: wswietse@heithe5 | Dept. of Mathematics and Computer Science surf: tuerc5::wswietse | Eindhoven, The Netherlands.

These driver tables can be uncompiled, modified, and re-compiled (or written from scratch and then compiled) using a package posted to comp.sources.unix a couple of days ago, Bruce Townsend's Nroff Driver Tables Utilities, v13i069. If the NROFF is version 2.0 or later, it has its driver tables in ASCII form, modifyable with any editor (i.e. vi), and stored in either /usr/lib/term or /usr/lib/nterm. BTW, Bruce Townsend's package includes a sample printer driver for HP-LJ+. Hope this helps. -- Wolf N.
