I got the details to guide you in backing up your QuickBooks data.
You can export your reports to Microsoft Excel 2008 and Apple Numbers 2009 (XLSX) or Microsoft Excel 2004 (SYLK). These are the supported software for QuickBooks Mac 2013.
About printing transactions, please refer to the QuickBooks for Mac 2013 User's Guide. You can find all the instructions for printing forms starting on page 261.
Feel free to post back if you have other questions. Have a good day!
