# Prevent scaling of printout of PDF without using hyperref

pdftex produces PDF. We need a viewer to view the PDF and print it. Some of those viewers tend to scale the printout: the letters shrink. This is a bug especially of the Adobe Reader and explained here: https://tex.stackexchange.com/a/204805/4736 .

A solution is describe here: https://tex.stackexchange.com/a/165348/4736 :

\usepackage{hyperref}
\hypersetup{pdfprintscaling=None}


I'd like to avoid hyperref, because it slows down compiling.

My question: Is there a command to do that without hyperref, maybe similar to \pdfinclusioncopyfonts=1? (To avoid a misunderstanding: \pdfinclusioncopyfonts=1 does somethin completely different, I'm asking if there exists something like \pdfprintscaling=0.)

## pdfTeX

The low level command for \hypersetup{pdfprintscaling} from the hyperref package with pdfTeX in PDF mode is:

\pdfcatalog{/ViewerPreferences<</PrintScaling/None>>}


## LuaTeX

As child of pdfTeX it inherits some of the functionality of pdfTeX. \pdfcatalog is enabled by package luatex85:

\RequirePackage{luatex85}
\pdfcatalog{/ViewerPreferences<</PrintScaling/None>>}


Without LaTeX/package luatex85:

\directlua{tex.enableprimitives('', {'protected', 'pdfextension'})}
\protected\def\pdfcatalog{\pdfextension catalog }
\pdfcatalog{/ViewerPreferences<</PrintScaling/None>>}


## dvips/ps2pdf

The special is:

\special{ps:[{Catalog}<</ViewerPreferences<</PrintScaling/None>>>>/PUT pdfmark}


## XeTeX

\special{pdf:docview<</ViewerPreferences<</PrintScaling/None>>>>}

• Heiko, I dropped a few lines about that here: komascript.de/node/1897 -- in German, of course. – Keks Dose Mar 13 '15 at 17:50
• @KeksDose In my document I use \usepackage[left=3cm, right=3cm, top=3cm, bottom=3cm]{geometry} \pdfcatalog{/ViewerPreferences<</PrintScaling/None>>}. The printer option is set to Page scaling: none: however, the left margin measures 3.5cm. How can I solve this problem? – Marco Jan 25 '16 at 18:06
• @Marco Ask a separate question here and provide a minimal working example. By the way, I put the command \pdfcatalog... always before the document class. – Keks Dose Jan 25 '16 at 20:44
• Any chance to achieve the same without pdftex? For example, with lualatex? – Twonky Mar 6 '18 at 7:30
