What has this to do with PDF? You are still somehow saying that you
need a level II printer to print from Acrobat Reader.

Sorry, but I came in when PDF was for on screen viewing. It happens
also to be printable. But the idea is to reduce the need to cut down trees.
I hear that recently people have pushed the idea of using PDF for high
quality service bureau work as well, but I remain sceptical of that.

I am not talking about PDF here. I am pointing out that of the two common
formats for publishing things on line the one that is *harder* to print reliably
is HTML. I have no trouble printing PDF, even on my level I printer :-)

Here we go again. I have a level I printer and never had trouble printing
from Acrobat Reader.

No resizing information is removed (whatever that is). And yes, partial
fonts are generated - just as with DVIPSONE (and now DVIPS). So the
`partial font issue' occurs in PS as well as PDF.

I didn't know that.
Personally, I have never come across an encrypted PDF file. On the other hand,
I have seen PS files zipped with a password...

? Isn't the licensing information on Acrobat Reader enough ?

The file you are referring to is plain vanilla PDF. It has purposefully not
been made using the latest bells and whistles (it is not optimized e.g.)
If a `PDF Reader' can't read it then it is not a PDF Reader. Of course,
I don't know what happened to the file on the way -

The minimum threshold for making quality PDF files from TeX is to have
a working PDF Reader. Without that the information in the file is of no use.

Really? When I click on a link that NetScape does not understand it will transfer
it in ASCII mode. Now you may consider this a bug in NetScape, and it sure
is irritating, but it demonstrates that file transfer on WWW *can* be done
incorrectly. I have to hold down the shift key to get it to do the right thing!
How large is the file you got after downloading?
If you continue having problems, ZIP it up and email it to me.
Or I can ZIP it up and email it.
Less chance of corruption that way.

I wonder whether anyone else has problems reading PDF files like
