See ?loadings and find that

  print(loadings(pca_object), cutoff=0)

shoudl print everything.

Although, if you want to use the loadings for generating graphics, you 
should work with the output directly, since thge information in the 
loadings object is much more precise than its pinted representation. Too 
see a bit more, type, e.g.:

l <- loadings(pca_object)
l[]
