I am having an issue with print on Safari. My System is Windows 7, and this function works fine in all other browsers except Safari. Here is the situation:

window.onload = function(){

    console.log('before print');

    window.print();

}

It won't output the log in console panel, but the print page will appear first, after i choose cancel in print page, the log will be output.

Does any body came up with this issue? Any help will be appreciated.

Here is the situation i have:
We need to print a page whose content can be changed by user by checking and unchecking check box, and only the content part of this page should be printed, so we create a new page that only contains the content for printing. In this page, we need to hide the unnecessary content that is not selected by user, so we need to do some DOM operation before window.print() get called. The console.log() is just an example code for observing. I tried to add an <div id='test'>Test HTML</div> in test HTML and add

var test = document.getElementById('test');

test.style.background = 'yellow';

before window.print();, it shows the same result in my Safari browser, the 'Test HTML' will not turn to yellow until i click cancel button in print panel, so it's not just the console.log issue.
