print small pdf file for a conference

For a IEEE conference paper, all fonts must be embedded in the pdf file.
The solution is print the non-embedded pdf file to the other pdf file.
One is CUPS-PDF, but the output file is strangely larger, and the version of the pdf is 1.3, which is lower than the standard.
The other driver comes from envince document reader, which is the default reader on UBUNTU. You can directly print the file as a pdf or ps file. The surprising thing is the size of the output file is small and all fonts are embedded.

Of course, the most simple one is use ps2pdf in the latex, use follow command:
"ps2pdf -dCompatibilityLevel=1.4 -dMAxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true -sPAPERSIZE=letter -dPDFSETTINGS=/printer ".

vim-latexsuit on ubuntu 11.04

After using apt-get to install this suit, it can not work still, but add follow lines in the .vimrc file, it start to work:


" REQUIRED. This makes vim invoke Latex-Suite when you open a tex file.
filetype plugin on

" IMPORTANT: win32 users will need to have 'shellslash' set so that latex
" can be called correctly.
set shellslash

" IMPORTANT: grep will sometimes skip displaying the file name if you
" search in a singe file. This will confuse Latex-Suite. Set your grep
" program to always generate a file-name.
set grepprg=grep\ -nH\ $*

" OPTIONAL: This enables automatic indentation as you type.
filetype indent on

" OPTIONAL: Starting with Vim 7, the filetype of empty .tex files defaults to
" 'plaintex' instead of 'tex', which results in vim-latex not being loaded.
" The following changes the default filetype back to 'tex':
let g:tex_flavor='latex'


set shiftwidth=4
set cindent
syntax on
colo desert


set spell spelllang=en_us
" zg to add word to word list
" zw to reverse
" zug to remove word from word list
" z= to get list of possibilities
set spellfile=~/.vim/spellfile.add
