Hi, at our workplace we use Firefox exclusively for our point-of-sale system and as such, print lots of reciepts and labels. We updated Firefox to version 82.0 this morning and now nothing prints correctly by default. When opening print preview, no matter what, it's a blank page. I have adjusted the settings in about:config, reset the print settings, messed with margins, etc. Basically every possible suggested fix for the problem I could find. After multiple hours, we still cannot get anything to print from Firefox UNLESS you go into the print settings, and click "preferences" in the Windows dialogue box (even if you don't change a single thing), only then will it work perfectly every time. This isn't an acceptable option though as we need it to work rapidly and automatically each time though the browser. Our printer is set up correctly, up to date drivers, etc. All programs in windows will print fine, Chrome and Edge print fine, so I'm assuming it's specifically a Firefox issue. This is a receipt printer, and I noticed Firefox defaults to 8.5x11 size paper despite it using standard 73mm receipt paper. But, like I said, no matter what the preview is a blank page and that's what prints. I'm stumped on this one. Printer is a TSP100 if that matters. Help!!
