How can I print a full page of the same label using Mail Merge fields? I
have a spreadsheet with hundreds of lines. I would like to select specific
lines and print a full page of labels for each of the selected lines.

I have only been able to figure out how to print one of each of the selected
labels.

Each time I print, I will select only the lines that are needed that run,
but will need a full page each time.
