Print scaling - force "Actual size"

[JOHO]

In Adobe Acrobat Pro it's possible to set "Page Scaling" to "None" in the advanced settings for the document. This forces the print settings to be set to "Actual Size" in Adobe softwares (not tested other software).
It looks like it's possible to set some metadata containing "/ViewerPreferences << /PrintScaling /None >> >>" to achieve this. See links below.

Does wkhtmltopdf support this? If not - can anyone of the developers look into it?

A command line argument would have been nice :)

I'd like to see this as well. A workaround I've found to work is to set a body size in CSS and print with --zoom 1.5. It seems to auto scale correctly.

Please create an issue on Github, so that this can be tracked.

This perl module can be used to set this option:
http://search.cpan.org/~ssimms/PDF-API2-2.020_01/lib/PDF/API2.pm

Simple script:

use strict;
use warnings;
use PDF::API2;
my $pdf = PDF::API2->open($ARGV[0]);
$pdf->preferences(-printscalingnone => 1);
$pdf->saveas($ARGV[0]);
