After you've installed the printer drivers for the various printers you'll use both those on-site for proofing and those at a service bureau or prepress house you should turn your attention to setting global printing defaults, the ones that affect all printing jobs, such as the use of paper trays and the handling of TrueType fonts.
Before you actually print, InDesign will check your document for possible output problems using its preflight tools. You also have the chance to create a print package which collects all graphics, fonts, and a copy of the document file to send to your service bureau or other output service.
