The Pack and Go Wizard will take you step by step through the complete process.
To start the Pack and Go Wizard:

On the
File menu, click
Pack and Go.

Click
Take to a Commercial Printing Service.
Using the Pack and Go Wizard is straightforward. The first thing you have to note is that there are two wizards: one packs a publication so that it can be conveniently transported to another computer; the other packs a publication so that it can be conveniently taken to a commercial printer. The differences are minor, but significant. Be sure that you select the wizard that packs the publication to take it to a commercial printing service, otherwise the packed publication you hand off to your printer may not be suitable for commercial printing.
