just to clarify, it is only supposed to print the 2 labels...that's the entire report, so to speak?
If so, I don't that there anything can do about it...CR says print this page and sends it to the printer, which prints the page and ejects it.
a more complex solution might be to tell the report how many rows of labels to skip before it starts printing so that the rest of the labels on the sheet can be accessed.
If it is that there are 2 labels in group, and then you have another group of labels to be printed, I would remove any new page before or after on the groups.
