Make sure that the records you want for your labels are in your found set.
Be sure to select "records being browsed" in the print dialog when yu print.
I am being brought to the layout by a script and it does only show me the record being browed but when I print it, it still only prints one label on the first, not the whole sheet of labels for that client.
Records being browsed is an option you select in the print dialog when you go to print your labels. If that option is selected in the print dialog, you will print all the records in your found set. If your found set consists of a single record, however, then you will still get just one label printed.
