If you're using Dymo Label V.8 software and, for some reason, your scanner is scanning the barcodes in, but when CB prints out their own, your scanner isn't recognizing them, here is the solution I sorted out. The fix was entirely inside Windows 11 → Settings → Printers & scanners → DYMO LabelWriter DUO Label → Printing preferences → Advanced, changing these four settings: Color Printing Mode → Default Halftoning → Auto Select Print Quality → Barcodes and Graphics Print Density → Light (changed from Normal) This should apply to the backend of the label maker you're utilizing. I'm attaching a step-by-step PDF as well. I'm groaning with you. I don't know where things changed in the scanning of my mini collection of 3.3k. I'm going to have to go back and redo them lol. At least that will allow me to reorder them. One thing I need to figure out is how to make a printable field on the label indicate a Box number. So instead of filling them in alphabetically, which can be a royal pain once you get to a certain point, you can print the box you're placing it in on the label. And also have that info on a printout of your master list. So if anyone has that answer, post below. I think I knew it once many years ago but lost that knowledge. ComicBase_Dymo_Fix_Guide_v2.pdf
