Tested the same on Firefox -> lower than 205 - 210 mm. Tested with printscaling on prawn at :appdefault -> Printed at 213 mm.

#CHROME AND DEFAULT PRINT WINDOW ON MAC PDF#

So naturally, i tested printing it through Chrome directly instead of opening the PDF through OSX -> Printed at 205 mm.

Selected the Print option -> Used Print Dialog -> Selected the printer -> Print Preferences -> Advanced -> Paper Size -> Changed scaling manually -> tested A4, A5 and so on.-> A5 ( for some reason gave me 213 )Ĭhanged Paper Size and tested the same : Size was 213 mm. This was less before ( around 205-210ish ). Printed the PDF in Chome : Perfect - 213 mm This is my test results from what i have seen by using a windows system and a Mac ( Yosemite ) I also tried making a webpage instead of a PDF and set the image width to 213mm which didn't work either. When I print a plain image or a website with Chrome there is a 'Use Original Size' or '100% size' option which I don't have when printing the PDF. Unfortunately I can't change the width of the image (not even a pixel).Īny ideas? It's an interesting puzzle I guess.

Github Repository with example image & pdf generator script If Imgur changes the resolution to 72, you can pull the example image from the repository (link: ) Here is an example 300 DPI image which width is 2515 px: The last one was touched 2013 but no one said anything that actually worked for my case. I looked through the Bugreporters of Chromium and found 2 people who might share the same problem as I do:

Tested under IE11 (205mm) unfortunately.

Tested under Windows Chrome (it's 213mm there, weird), maybe it's related to MacOSX Chrome?.

Playing around with various settings provided by the Chrome Printer Dialog.

Playing around with print_scaling(there are 3 modes, :none, :AppDefault, :something_except_the_other_ones (Read more about it here).

Setting the prawn page_size to something lower than A4 (since the Image isn't bigger as A4 as well.).

The printed PDF will show an image with 205mm width. The printed PDF will show an image with 213cm width.

I create the Image using RMagick but the size, dpi and everything so far seems to be alright. The Image nested inside the PDF has a size of 213mm x 70mm with I use prawn to dynamically create a PDF A4 (landscape format) using this code: require 'prawn'

Let me explain more about my code so far: dynamic PDF: This doesn't happen neither in Adobe Reader/Acrobat/MacOSX Default Printer Dialog. When I try to print a dynamically created PDF using Chrome ( also in Firefox), every image inside the PDF gets a little bit smaller (8mm). Today I encountered one weird bug in Chrome's printing behavior.
