Having recently moved from Quickbooks POS we upgraded to the Zebra ZD421. When we print from the Retail Barcode app the barcode itself is basically just a few black boxes. If we go into the printer settings and change the graphics type to clipart then it will print the barcode correctly where all the individual lines are there and can be scanned. We cannot figure how to get it to remember the setting or have the app actually send the right commands to the printer. Any ideas?
