Follow these steps to properly configure your DYMO printer and ensure your labels print clearly and align correctly in AccelerList.
1. Download and Install QZ Tray, then Open Printer Settings in AccelerList
First, make sure you download and install QZ Tray.
Then navigate to:
Settings → Printer → SKU + FNSKU Labels
