The margins that were set by default in labview are small for some printers, then you should:
1.Open the block diagram of the Text Report Example.
2.GO to the block diagram of the "Initialize Report.vi" situated at the left hand side of the diagram.
3. There will be a cluster constant where the margins are settled to 0.5 & 1.00, this cluster is conected to the margins(1.0) input of the "Set Report Margins.vi", play with them and it will work, save the vi to the margins you found more confortable to your aplication. I usually set it to 3.00 all of them to avoid any problem caused by this vi, an normally this will leave you alone in any pc.
