Hey romanovsky,
The cloud-based nature of QuickBooks Online ensures you'll always have access to your financial information, but printing off important reports is a great way to keep a physical backup. The system comes prepared to help you print your reports, so you can always have a copy for your records. The best way to ensure your General Ledger fits all columns on a single page is to adjust the Scale to Fit to page from the print dialog.
Hope this helps!
