Hello:
I found a rather rare bug involving latex, dvips, PostScript Times,
and/or HP LaserJet 4si printers. I don't know which one of them screws
up, and if you're out of luck it's a combination of a few of them.
Some groups of letters are cut from the remainder of their line and
shifted about half an inch to the left. These letters are written on top
of existing text, and a blank space appears to the right. As I said,
this is rare, but I have two examples for you.
In my directory:
/afs/athena.mit.edu/user/o/l/oledoit/Public
you will find:
bug.aux bug.log bug.tex mitthesis.sty
bug.dvi bug.ps bug_fixed.ps
I obtained bug.dvi by doing:
latex bug.tex
I obtained bug.ps by doing:
dvips -o bug.ps bug.dvi
I obtained a hardcopy of the bug by doing:
lpr -Ppicus bug.ps
There is no indication that the bug is particular to picus.
The bug is on lines 5 and 8.
I fixed the bug myself by changing bug.ps into bug_fixed.ps
In order to see what the page should look like, I did:
lpr -Ppicus bug_fixed.ps
What I changed can be seen by doing:
diff bug.ps bug_fixed.ps
The result is:
342c342
< (inner)h(pr)l(oduct)e(is:)37 b Fh(S)3416 1169 y Fc(1)3476

---
> b(stocks:)35 b(it)25 b(is)g(about)f(as)i(bad)f(as)g(using)f(two)h
As you can see, I didn't have to change much to fix the bug.
Interestingly, the bug does not appear when I do:
dxpsview bug.ps
or:
ghostview bug.ps
But it does appear when I do:
dvips -Ppicus bug.dvi
I hope you can use my report to find the origin of the bug and fix it at
the source, or issue a warning in olc stock answers.
Please keep me informed of what you find.
Good luck!
Olivier Ledoit.
