Hi. I always use Firefox to print ebay postage labels. Recently when I print labels firefox seems to miss out labels and just prints blank pages in there place. Does anyone know a fix for this. I have checked and Firefox is up to date and Adobe is set for my Portable Document Folder. I am literally tearing my hair out as I need to use chrome and then adjust margins but still each label seems to move up or down slightly to the point where half a label will appear on the next page. Firefox was fine up until recently. Thanks
