[Tex/LaTex] Exclude images for printing pdf

graphicspdfprinting

I have a document that has images that are very, very dark. As such, they should not be printed when the user goes to print. Somebody I'm working with loves to print, and they use a lot of toner this way.

Is there a way to make an image not print in the hard copy paper view, but show up in the electronic view?

If you are using pdflatex or lualatex, pdftex.def allows you to specify an alternate image to be used for printing:

\includegraphics[print=print.png]{screen.pdf}

This will probably only work with Adobe Reader.

You could tell pdfTeX about the resolution:

\pdfimageresolution96
Or specify it to \includegraphics:

\includegraphics[resolution=96]{filename}
Or declare it globally:

\setkeys{Gin}{resolution=96}

You may try putting the following code, extracted from the package syntonly, just before \begin{document}

\usepackage{array}
\makeatletter
\font\dummyft@=dummy \relax
\dummyft@
\tracinglostchars=\z@
\count@\sixt@@n
\loop
\ifnum\count@ >\z@
\advance\count@\m@ne
\textfont\count@\dummyft@
\scriptfont\count@\dummyft@
\scriptscriptfont\count@\dummyft@
\repeat
\let\selectfont\relax
\let\mathversion\@gobble
\let\getanddefine@fonts\@gobbletwo
\pagestyle{empty}
\let\ps@fancy\ps@empty
\let\hline\relax
\newcolumntype{|}{}
\let\cleardoublepage\relax
\makeatother

This should ignore all text, but include images, printing as many as possible on each page.

I've added some of the more frequent commands that need to be "neutralized".

Alternative approach

Add the following to the preamble:

\newwrite\figurewrite
\immediate\openout\figurewrite=\jobname-figures.tex
\let\includegraphicsORI\includegraphics
\renewcommand{\includegraphics}[2][]{%
  \immediate\write\figurewrite{\unexpanded{\includegraphics[#1]{#2}}^^J}%
  \includegraphicsORI[#1]{#2}}

Compiling your document (say thesis.tex ) will write a file thesis-figures.tex containing the relevant \includegraphics commands and it's just a matter of adding a suitable preamble in order to compile this file.
