Do any transactions get selected for the report? Or do you essentially get a blank page?
Some reports that rely on temporary work files will not print the company profile name in the title, because no work file gets generated when zero transactions are selected by the report.
Bruce's answer is the first place to check. If your company name is there, then the next thing to check is whether your aged trial balance actually selects any invoices. If not, you will need to refine your choices when printing the report to ensure invoices are selected.
One common mistake is that a range on the report is from blank to blank. Ensure ranges that you want everything selected go from blank to zzzzzz.
