pacolley@violet.uwaterloo.ca (Paul Colley) (04/19/91)
In the best Usenet tradition, here is a summary of my quest for
a working DVI driver for the HP DeskJet 500.
Wed Apr 17 08:21:01 EDT 1991
I received a minimal set of Beebe files and a "dvidj.c" which was
supposed to be a DeskJet driver, from an individual who hadn't yet
been able to test it.
After much frustration (involving the fact that the output was
"horizontally hashed" into unreadability), I asked the person who
sent it to me if he had tried it yet; didn't work for him either.
<sigh>. He recommended a commercial TeX package that included
the DeskJet driver.
Refusing to buy myself out of my problem (budget more than pride
being the issue), I asked the newsgroup for help.
The response from the newsgroup was enthusiastic and helpful.
Among the responses were a "dvidjp.c" which was supposed to work
with the Beebe files. I downloaded the Beebe files from
ymir.claremont.edu, added the dvidjp.c, and compiled. The resulting
executable had the peculiar habit of destroying the input .dvi
files. After destroying the .dvi file, it (correctly) noted that
it was no longer in the correct form for a .dvi file and refused
to print it. Hmmm...
Rather than trying to debug that, I next tried the "dvidjp.c" with
the set of Beebe files that were sent to me with "dvidj.c". Voila!
Success! Or... maybe not... When the inital rush wore off, I
noticed that no horizontal or vertical lines were printing (dashes
printed, but not over/under lining or lined tables or footnote-separators).
After some abortive fiddling with the font files looking for a
non-existent problem, I discovered that the "fillrect" code was
commented out in gblprocs.h and setrule.h as they were sent to me
in the "dvidj.c" set. Replacing them with the files from the Beebe
set resulted in a "dvidjp" executable that works, as far as I can
tell, perfectly.
And that's where it stands now.
----------------------------------------------------------------------------
O.k., now for the comments:
Much thanks to all who helped. I hope I haven't missed anyone, but
the list includes:
Steve Orr (steveo@world.std.com)
Paul Reilly (reilly@dg-rtp.dg.com)
Meinhard E. Mayer (?) (hardy@golem.ps.uci.edu)
Fred Appelman (fred@cv.ruu.nl or appelman@cs.unc.edu)
Bob Hepple (bhepple@Asia.Sun.COM)
With special thanks for Paul Kirkaas (kirkaas@cs.ucla.edu) who
wrote and sent me the dvidjp.c code.
In addition, I recieved many requests for the driver, so I will
post the source to dvidjp.c separately.

The stuff that I sent you seems to behave the same as it did when
I tried it. I solved the problem by being contacted by a Mike
Grenier who owns a joint called ScandiaMicrosystems. They provided
me (for a fee) with the binaries for the TeX/Metafont system, groff,
xdvi, and a few other related goodies. Also comes with all of the
TeX font libraries etc. BUT! The biggie is that it comes with a
dvitodj that really works. That alone makes me feel good about
about throwing money at him.
I can recommend this stuff to you highly.
Mike Grenier: 612-464-6056 or texinfo@cimcor.mn.org
He took my Visa number over the phone and was very responsive when
I had a couple of installation questions.
BTW. I am just about to complete this little fiasco by acquiring
the src code for the whole shebang tomorrow.

A somewhat cryptic note:
(Changing the DIP switches did not help me, but I've included it
anyways included anyways...)

I have compiled it on an HP 9000/370 and it runs fine on a deskjet
plus. I had similar problems originally and traced them to the
printer switch settings! which are left-toright:
dddudddd uuuddddd.
I have placed a tar-file (with modified cmakefiles and headers) in
pub for anonymous ftp, if you want to try again.
But play with the switches first!

A recommendation for a MS-DOS solution:
From: Fred Appelman <fred@cv.ruu.nl>
Subject: Re: DVI driver for DeskJet500 WANTED
If its a IBM PC, use emtex. I have the same printer and it works
fine with the 'prthplj' driver. You have to supply some options to
the driver telling it, it's actually a deskjet. After that the
result is great.

Again, thanks for all those who sent code and offered suggestions.

The following letter and accompanying code from Paul Kirkass was the
solution to my problems. The DVI driver it produces works perfectly
for me.
----------------------- CUT HERE ---------------------------------------------
Enclosed is a a file to be used with the Beebe driver distribution.
The DeskJet500 should be the same as the deskjet plus.

/*
I just got myself a brand new HP Desk Jet Plus printer to use with TeX.
I and a number of other people asked the net for sources to one of the many
DeskJet drivers which must be out there, but there was no response. I
searched all the archives I could find, with similarly unsuccessful
results.
So I took the dvijet driver from the Beebe release and modified it for
the desk jet plus. It might be called (as by some) a "vanilla" driver
because it doesn't use downloadable fonts, but downloadable fonts
requires an extra memory cartridge -- for that I would have just
as soon bought the IIp. I did include some memory compaction, though,
which reduces file size and transfer time by 50 - 70 % So it's not
quite vanilla. The various compaction schemes can be switched off
at compile time if the old Desk Jet doesn't support them (I have no
idea).
I include the modified source below. It requires the rest of the
Beebe driver code, which is commonly available -- eg,
at ymir.claremont.edu & science.utah.edu in aps:<tex.dvi> ... whatever.
Be warned that the whole BEEBE dvi package is about 1MB. This file is
only a tiny part of it.
Hope this is helpful.

/* Driver for HP DeskJet Plus printer -- modified from
* Beebe Laser Jet driver
* by Paul Kirkaas (kirkaas@cs.ucla.edu) 22 May 1990
* patch 1 -- bugs in YOFF & COMPACTION fixed 23 May 1990
*
* Employs 3 types of data compaction for greater efficiency --
* up to 60 - 70% reduction in output file size. Each compaction
* scheme can be switched on or off independently by defining any
* or all of:
*
* XOFF -- X offset -- instead of a string of leading zeros, offset
* by appropriate amount. Minimal savings when used with
* COMPACTION mode set.
*
* YOFF -- Y offset -- compress multiple blank lines into a single
* y skip command.
*
* COMPACTION -- Uses mode 2 compaction on Desk Jet Plus -- this is
* the trickiest but most effective compression modification.
* This is the likliest part to have a bug.
* Lots of cleaning up can be done here.
*
* If you have an old Desk Jet (not a Plus) it may not have
* all these abilities -- try undfining some of these switches.
*
* It should run straight with the Beebe driver set; you might
* have to make some adjustments. I have personally only run
* it on an AT&T System V 3b1.
*
* Please let me know if you make any improvements or repairs.
