Hi Ana,
Thanks for the reply. I'm adding those into the drives. BTW,
900 is the value. Having no real experience with these, is it
abnormal for a load to take the 10+ minutes, or is that reasonable?
My next step is to add those settings in, restart the SD, and attempt
to do a "label barcode" again.
Thanks,
Andrew
