There's probably a better way, but the method that comes to mind is to create a one-field table and put data in the single field to create the same number of records as there are labels per page (the actual data doesn't matter, it will not appear anywhere in your report). So if your labels are 30 per page, put 30 records in your little table. Then include that table in the query that is the basis for your report (or create a new query that uses your original query and this table). That will force the query to generate 30 instances of each label - voila! - one page per record.
