Have you tried repairing Excel (Help|Detect & Repair)?
Check too that the workbook's page size is no larger than the paper onto which the pages are being printed and that the page margins are at least as large as the minimum margin requirements of the printer on which they're being printed. File|Page Setup|Page will show the paper dimensions the Excel worksheet is set up for, whilst File|Page Setup|Margins will give you the Excel margins. Your printer's settings will tell you what paper stock it has and the printer's minimum margin settings.
Of course, it's also possible there's some corruption in the Excel workboook.
