There was an Adobe update this morning, did you install that? If so, bad things always happen with C&S for a day or two afterwards.

What l normally do (because the printed labels are so faint and fuzzy), is once the label box has opened up, l select 'open with another application', print the label out with the PDF printer. They come out crisp and clear.

It's a fault with C&S that has only started since the labels went downsized. They aren't going to fix it in a hurry so finding a work around was vital. Takes more time but at least the post office can scan the barcodes now.
