(I sent the mail again because it seems to be lost)

I'm sorry, I was not clear:
600 ppp for text ("Resolution des graphiques EPS") - somebody on this
list or IRC told me that.
And images uncompressed (I mean: the images are uncompressed, they are
not at 600 dpi -> our images are at 300 dpi, sometimes a bit more
(because at 300 dpi and reduced a little bit))
I could decide to compress the images at 300 dpi, but I'd rather use
absolutely no compression before sending the pdf to my printer.

One solution could be to compress the images when making the pdf, print
the pdf, check everything is ok, and then re-make a pdf with no compression.

But, as you can think, my project is to check the last pdf that I made,
just before sending it to the printer - because it's the one wich will
be printed!

The other solution is to open the pdf on a windows machine and then
print them - but it's not wonderful...

The bad thing is that in the past I could print some huge pdf without
any problems.

Thanks
