Welcome to the HP Support Forums. I gather that you would like to learn how to print envelopes using your Photosmart 5520 printer.
I have included the Photosmart 5520 User Guide. On page 15 it will walk you through how to load the envelopes into the printer. I have also included the Photosmart 5520 Printer Specifications. It has a chart with the supported envelope sizes.
