When you click the "3-bar" menu button and then Print, Firefox should show a preview of how the page will look when printed. I'm puzzled why it doesn't. If you use one of these methods to call up the print dialog, does that work: * Ctrl+p * tap the Alt key to activate the menu bar > File > Print If those don't work either, you may need to clear the information Firefox has stored about your printer. This article describes how you can do that: [[Fix printing problems in Firefox]].
