One hour, it is the time needed to find on the web a working workaround for that totally silly functionality added on Google Chrome.
But first, Google People, please tell me WHO really wants to have as default a print system that print in black & white ? Are you just crazy guys ??? WTF ???
Well, if you’re just like me and want to get the default print window back :
1) Open a Terminal (Applications / Utilities / Terminal)
Then copy/paste the following command :
defaults write com.google.Chrome DisablePrintPreview -boolean true
Finally, if you want this crazy print preview to get back, do the same but with the following line :
defaults write com.google.Chrome DisablePrintPreview -boolean false
