Debugging print preview in Chrome

Every web developer has had to deal with this.  Open up the print stylesheet…make some tweaks…open browser…open print preview…close print preview…make more tweaks…open print preview…etc.  And yeah yeah yeah…there is a way to emulate the print css in the browser, but that doesn’t do squat when trying to adjust content to fit the width of whatever page standard you’re supporting (letter/A4/etc.)

Well, here’s a bit of a shortcut for at least the closing/opening of print preview.  Open the print preview window, right click on the preview, and click “Inspect Element”.

Go into the javascript console, and paste this in:

setInterval(function() {
    this.printPreview.previewArea_.previewGenerator_.pageRanges_ = null;
}, 3000)


That will refresh your print preview window every 3 seconds.  My plan is to expand on this, and make it a Chrome plug-in that listens using an observer.
