packaging Indesign files for the printer

The remarks made a very valid, yet what you asked for goes as follows:

1. Open your file in InDesign.
2. Go to File > Package.
3. Click the Package button at the bottom of the summary window.
4. You will be asked to save your file.
5. Click continue on the “Printing Instructions” window. We do not use the information on this page so you don’t need to fill it out.
6. Browse to where you’d like to create the package folder (desktop would be fine) and enter the name of the folder. At the bottom of this window, make sure that the “Copy Fonts”(if licensed), “Copy Linked Graphics,” “Update Graphic Links in Package,” “Include Fonts and Links from Hidden….”, “Include IDML” are all checked. Other boxes should be unchecked unless you also need a PDF.
7. Click the package button.
8. Find the new folder that InDesign created and verify that it contains copies of all required files.
9. Zip your files.

Is your printer asking for the InDesign files, or are they going to output the PDF you provide?

If it’s the latter then you don’t need to package. Export to  PDF (Print) using one of the PDF/X presets—PDF/x-1a if the printer wants all CMYK with no live transparency, or PDF/X-4 if they prefer to flatten transparency at output.
