So can I assume you are actually using Thunderbird? and not having printing issues in Firefox (two versions) and Windows. # Open the troubleshooting information. (☰> Help > Troubleshooting information) # Open the search bar (ctrl+F) # Search for Printing. (you might have to click the down arrow to get the heading printing, or it might be the first result to appear) # Use the shown "clear saved print settings" button Any better? If not try the troubleshooting mode and report your results. (☰> Help > Troubleshoot Mode)
